Description

The present invention relates to the field of communication technology. More particularly, the present claimed invention relates to a method of configuring a configurable communication device and to an electronic device and to a computer-readable medium of electronic device.

The WO 99/23762 A1 describes a system and method for providing a digital, radio frequency, field-configurable communication system that may be configured in a transmitter or a receiver to function with a variety of signaling schemes, e.g. AM, AME, A3E, H3E, J3E, CW, SSB, M-PSK, QAM, ASK, angle modulation, including FM, PM, FSK, CMP, MSK, CPFSK, etc. The system includes nonvolatile memory adapted to receive and store instructions for configuring the system. A user selects the mode of operation and the signaling scheme, and instructions and software are loaded from memory into the system and configure the system according to the user's choice.

Wireless communication has many applications in private and industrial markets. Spread spectrum techniques are becoming increasingly important as a method of transmission in a wireless communication system. Among the many spread spectrum communication applications / systems are: fixed wireless, unlicensed wireless communications from the Federal Communications Commission (FCC), local area networks (LAN), cordless telephony, personal base stations, telemetry, Mobile and other digital computing applications. While each of these applications uses spread spectrum communication, they generally use special and incompatible protocols for various signal processing operations, such as encoding and decoding, modulation and demodulation, etc. These specialized and incompatible protocols often require special hardware, software, and communication protocol techniques , This approach can be costly in terms of design, testing, manufacturing, and infrastructural resources.

In addition to the differences between spread spectrum communication applications, significant changes within a given spread spectrum communication application occur over time. For example, within the cellular, code division multiple access (CDMA) spread spectrum application, significant changes have occurred over time. These changes occur in the form of a variety of different versions and performance levels, eg. Inter-standard 95 (IS-95) CDMA, broadband CDMA (WCDMA), 3GPP, etc. And the speed with which improvements and new standards are emerging is increasing as more industrial resources meet the needs and opportunities within the wireless Be contracted together. Unfortunately, all of these factors lead to minimal uniformity in the world at any one time. For example, different countries and different service providers often use systems that are specifically adapted to their specific version of a communication protocol.

If a single device were able to overcome the deviations within a spread spectrum communication protocol and the deviations over time within each protocol, it could provide a common solution. Such a device would have to be of a generally generic nature to accommodate such a wide variety of functions and applications. However, such a universal device would typically not be able to perform any of the various applications alone, for example in its manufacturing state. This is a fully expected drawback of generality in the design for versatility in a potential application. Thus, a need arises for a method of overcoming the limitations of a universal spread spectrum device to perform a specific spread spectrum application.

Given the internal ambiguity of a universal spread spectrum device, a substantial amount of external control information will be available to adapt to a specific application. While a user could manually provide external control information to the spread spectrum universal device, this would be time consuming and inefficient. Furthermore, given the complexity of a universal device that would be required to allow the device to perform a wide range of complicated and compute-intensive algorithmic data processing operations, the success of such a manual operation would be unlikely. Consequently, there is a need for a method to overcome the limitations of manually programming a universal spread spectrum device.

Furthermore, with the large amount of variables and subcomponents in such a device, there would be many different combinations and permutations of hardware connections and Variable assignments possible. Consequently, it would be highly probable that errors, glitches, malfunction or even inability to operate would occur. Furthermore, other complicated issues, such as clean timing and sequencing, memory addressing, and adapting algorithmic assignments for a universal spread spectrum device would be cumbersome tasks. Consequently, there is a need for a method for overcoming the problems of working with a full set of possible combinations and permutations of hardware sequencing and variable assignments.

Even if it were possible to successfully set the universal device for a specific application, verification of the settings could be difficult. For example, a device could operate acceptably with a set of variables. However, this performance can not guarantee that the device will work successfully in another scenario. Consequently, the need arises for a method and apparatus for verifying and simulating the operation of the general purpose device that receives external control information for a specific application.

Referring now to 1A 13, a block diagram of a configuration system according to an embodiment of the present invention is shown. A configuration system (or a programming interface system) 100a includes an external processor device 102 and a configurable communication device 104 , The external processor device 102 includes configuration information 103 stored in a memory for the configurable communication device. The external processor device is a workstation in one embodiment.

The configurable communication device includes two computing elements in the present embodiment 106 and 108 passing through a line 107 are coupled. The administration 107 In one embodiment, it is a configurable connection unit that selectively selects the elements 106 and 108 or parts of it. An exemplary configurable communication device 104 is incorporated in co-pending U.S. Patent Application Serial No._______, entitled "A wireless spread Spektrum communication platform using dynamically reconfigurable logic ", with the lawyer's reference 9824-0035-999 shown. This related application is co-pending and is hereby incorporated by reference into the content of the application.

The configuration information 103 from the external processor device 102 is through an interface 109 transmitted to the configurable communication device. the interface 109 is a wired communication connection that is the external processor device 102 and the configurable communication device 104 coupled in one embodiment. In another embodiment, however, the interface is 109 an electronic storage medium, such as a CD-ROM and host, the configuration information 103 for the configurable communication device. In yet another embodiment, the interface is 109 a wireless transmission from the external processor device 102 or another communication device, for example a wireless base station or a wireless test platform.

In another aspect of the present invention, configuration information is provided for the present embodiment at the time that the configurable configuration device 104 produced and / or programmed for the first time for operation in the field. In another embodiment, however, configuration information is dynamically provided at a time at which the configurable communication device 104 in the field is in operation.

External computing device

Referring now to 1B 13, there is shown a block diagram of configuration generating functions performed by an external processor device according to one embodiment of the present invention. The block diagram 100b provides an exemplary functional basis for generating configuration information 103 from 1A Ultimately, this is the configurable communication device 104 to configure.

The functional block diagram 100b includes a configuration generating function block 110 which is able to receive data and command information and provide configuration output information. In particular, the data information relates to the user-desired configuration of the configurable communication device 104 from 1A , In contrast, command input information is instructions for one or more applications through the configurable communication device 104 to be realized. An example of such command input information is industry standards, communication protocols, etc. In addition, data input information provided by a user may include proprietary algorithms and methods that operate within the limitations of an application protocol and are covered by its latitude. Finally, the configuration output information relates to the configuration information provided by the configuration generating function block 110 which are the configurable communication device 104 from 1A allow you to work according to the user's input data and command data for the application.

As an example of user-provided data inputs, a user could provide desired application input information 114a as a "wireless local loop" (WLL) for which the configurable communication device is to be configured. Similarly, the desired functional input information 114b be defined by a user as a modulation function for which configuration information must be determined to be the universal configurable communication device 104 to operate. The desired input information 114c may refer to the format in which data awaiting the computational element configured for modulation within the configurable communication device is expected. This input format may reflect other proprietary or unique custom data processing techniques that prepare and format the data for the subsequent modulation function. The desired output information 114d correspond to the user-requested format of the output data. While a communication protocol, so to speak, tightly defines the format and method by which data is transferred between multiple devices, the format and method of processing data within a device is up to the user ( for example the device developer). In this way, a user can develop and implement custom proprietary and non-proprietary algorithms and operations adapted to the user's needs, such as finding a compromise of quality of service (QOS), power consumption, etc.

The command input information to the configuration generating function block 110 include, among others: 1) a library of functional input information 116a . 2 ) a calculation resource input information 116b for the configurable communication device and 3) protocol format input information 116c , An example of a library of functions would include standard configurations or functions provided by the configurable communication device 104 be adjusted. In one embodiment, the library may include functional input information 116a Include functions that are common to multiple applications, thus allowing for close customization by a user. An example of a calculation resource input information 116b can be the number of available computing elements (for example, the computing elements 106 and 108 from 1A ), the flexibility of each configurable connection unit (for example, the configurable connection unit 107 from 1A etc. etc. for a given configurable communication device, such as a device 104 from 1A , include. Lastly, an example of protocol format input information 116c Include rules and definitions dictated by a protocol to which the configurable communication device is intended to conform, such as rules for syntax, format, timing, etc.

Furthermore, this information is provided for these elements and sub-components at different times of a processing cycle. The output information for timing sequences 118b includes information, such as when certain computational elements realize a specific configuration, when certain computational elements are selectively coupled, and when certain computational elements are enabled to perform their operations and functions. Finally, an example of a connection configuration is included 118c Information that defines which computational elements are coupled together and which subcomponents of computational elements are coupled together. Example user-definable data inputs 114a to 114e , Command inputs 116a to 116c and configuration outputs 118a to 118d are provided in the scope of the detailed description and in Appendix A of the patent application "A WIRELESS SPREAD SPECTRUM COMMUNICATION PLATFORM USING DYNAMICALLY RECONFIGURABLE LOGIC", which is incorporated by reference.

Referring now to 2 13, there is shown a block diagram of a computer system used to connect a user to a configurable heterogeneous multiprocessor device according to an embodiment of the present invention. A computer system 120a Fig. 3 illustrates an example implementation of the external processor device 102 from 1A available, which is the configuration-generating function block 110 from 1B allows.

The computer system 120a includes a nuclear unit 220 that have a control / data bus 202 for transmitting information, a central processing unit 204 to process information and commands by bus 202 is coupled and a storage unit 206 to store information and commands by bus 202 is coupled. The storage unit 206 may include a memory configuration, such as random access memory (RAM), for storing temporary information and instructions to the central processing unit 204 , In addition, a non-volatile memory 208 comprise a memory configuration consisting of "read only memory" (ROM) for storing static information and commands for the central processing unit 204 , A data storage unit 210 can store program commands and extensive database type information.

The computer system 120a Also includes an optional display device 218 , The display device 218 may be any type of display, such as an analog or digital display unit. The computer system 120a also includes an optional input device 216 that by bus 202 is coupled. The optional input device 216 may include any input device, such as an alphanumeric input device, such as a keyboard or pointing element, such as a mouse, etc. An optional input / output signal unit 212 provides a communication interface of the computer Systems 120a available, for example a serial interface etc.

The bus 202 FIG. 10 illustrates an exemplary docking configuration of devices in the computer system 120a to disposal. The bus 202 is shown as a single bus line for the sake of clarity. It is obvious to the person skilled in the art that the bus 202 Subcomponents of specific data lines and / or control lines for the transmission of commands and data between corresponding devices may include. It is further obvious to the skilled person that the bus 202 may be formed in a parallel configuration or a serial configuration and that the bus 202 Connection units, gateways and / or translators, as appropriate for a given application.

It is also obvious that the computer system 120a by way of example only, and that the present invention may be practiced within a number of different systems, such as in a general purpose computer system, a dedicated workstation, an embedded system, etc. Furthermore, the present invention is well suited to use a host of smart devices having similar components as the example computer system 120a ,

Realization of processes in flowcharts

Referring now to 3 13, there is shown a flowchart of the process used to design a configuration of a configurable electronic spread spectrum communication device according to one embodiment of the present invention. A flowchart 3000 provides example steps and an exemplary sequence of steps by which the configuration system 100a , the functional block diagram 100b and the computer system 120a can be operated harmonically to enable the present invention. The present flowchart provides efficient, robust and timely configurable operations for a configurable communication device. The flowchart 3000 is generally realized to use the immediately preceding figures.

The flowchart 3000 starts with the step 3002 , In step 3002 In the present embodiment, input information is received at a computer identifying a desired function that the configurable device is to perform. For example, in one embodiment, it is possible for a user to select a communication (or arithmetic) function, such as modulation, demodulation, encoding, or decoding, as in FIG 1B shown. However, the present invention is well-suited to realize any type of function within the operating range of the configurable hardware. The step 3002 is in one embodiment through the entrance 114a from 1B realized that the computer system 120a from 2 is provided, wherein a user input data via an optional input device 216 , or from the storage units 206 . 208 or 210 of the computer system 120a in 2 provides. A user may, in one embodiment, perform any desired function for the step 3002 enter in a software library of functions 116a is available, for example Java, the programming language C etc.

In particular, a user may benefit from the hierarchical approach of the interface, including the idea of extensible data types, to take advantage of the inherent flexibility of the architecture. The desired function may be a "high-level" function, such as a modulation, which may be further divided into more discrete sub-functions, depending on the degree of programming desired for an application and in the library of functional input information 116a is available. Appendix A of the patent application "A WIRELESS SPREAD SPECTRUM COMMUNICATION PLATFORM USING DYNAMICALLY RECONFIGURABLE LOGIC", which is incorporated herein by reference, provides an exemplary list of modem and encode / decode functions and programming tools for which hardware cores ( or computing elements) 106 and 108 from 1A can be configured for an example spread spectrum application. The present invention is well suited to a wide range of data processing functions and cores that are passed through the step 3002 can be programmed. The step 3002 For example, a list of these subfunctions or operations may be provided to the user via a graphical user interface (GUI) on the optional display unit 218 from 2 for use in subsequent steps of the flowchart 3000 provide.

In the present embodiment, the list of functions provides a one-to-one mapping to the computing elements 106 and 108 from 1A and is therefore limited to it. However, the present invention is well suited to the step 3002 to realize with different degrees of functional granularity. For example, in a typical WCDMA application, the determining computations are centered around five major signal processing functions: "chip matched filtering", "code epoch search", chip demodulation / despreading, symbol rate processing, and Channel decoding. A user has the possibility to completely change the connection between these groups or to bypass the group (s) via the use of an interface in the configurable communication device. In this way, the ability of the data flow-specific configurable connection units between islands of compute cores can be fully exploited. In the flowchart 3000 follow the step 3002 the step 3004 ,

In step 3004 In the present embodiment, input information is received at a computer identifying a desired sub-function within the given function or a desired operation within a given sub-function for execution on the configurable device. The step 3004 In one embodiment, it is implemented in the same way as the step 3002 , A user can enter any desired, or none, sub-function present in a programming template that serves as a library of function input information 116a from 1B is made available. The programming template can be any type of appropriate programming language. For example, in one embodiment of the present invention, a list is provided of the functions in a data core specification list from which a user can select demodulation and encoding / decoding functions. The data core specification list is described in Appendix A of the co-pending application "A WIRELESS SPREAD SPECTRUM COMMUNICATION PLATFORM USING DYNAMICALLY RECONFIGURABLE LOGIC", which is hereby incorporated by reference. For example, a user may select a sub-function of code modulation within the larger function of the modulation. In the flowchart 3000 follow the step 3004 the step 3006 ,

In step 3006 In the present embodiment, input information is received identifying desired settings for a desired function. Input information for the step 3006 include, among other things: input and output (IO) parameters 3006a , determined by and for a function that is realized in a computing element, for example the elements 106 and 108 from 1B , Similarly, the input information includes the step 3006 also parameters and format inputs 3006B to specify internal operating parameters for the function by the computing elements of a configurable device 104 from 1A will be realized. A specification list may provide different inputs, outputs, and parameters available for designing a user-configurable device configuration. While the present embodiment provides specific selections of input information, output information, and parameters, the present invention is well-suited to use a wide range of options as desired for a given application. A set of available resources {Ri} as input information 3006C becomes the step 3006 also provided for the calculation. The input information 3006C represents the set of basic primitives, such as the computational element 106 from 1A , which is located in the configurable communication device 104 located. The available resources {Ri} are provided in the communication device design based on expected functions, subfunctions, and operations provided for protocol deviations, possible algorithmic flexibility needs, projected future algorithmic and protocol-related growth, and indefinite items. In one embodiment, the resources of a given configurable device may be stored statically in a memory of a computer system 120a from 2 to provide. Alternatively, the resources of a given configurable device may be determined dynamically by calling components of a configurable device, such as the communication device 100a , via a coupling arrangement (wireless or serial / bus hardware) to the computer system 120a , In the flowchart 3000 follow the step 3006 the step 3008 ,

In step 3008 In the present embodiment, a signal flow path (or diagram) of the desired mode of operation is generated. A signal flow path is a list of interfaces, such as the selected input and output types and formats, for a given function. The step 3008 In one embodiment, this is done by the processor 204 from 2 realized, which selectively the desired connections between configurable elements (for example, the elements 106 and 108 from 1A ) maps to the allowed connections that are available in a given configurable communication device. Consequently, input information becomes 3008a of a set of allowed connections {Ci} to the step 3008 provided for the calculation. In the present embodiment, the allowed set of connections {Ci}, for example hierarchical connection configurations of the configurable device, are provided by a programming rule, for example the library of functions 116a from 1B , The input information 3008a represents the amount of reconfigurability that is provided within a hardware core and between hardware cores, for example via the reconfigurable connection unit 107 from 1A ,

The step 3008 involves the creation of an original system data flow. The original system data flow can be generated from a written specification and system simulation. Specific algorithmic threads are identified from the original system data flow. The specific program threads are identified by a ranking of computational complexity in the present embodiment. One embodiment of the hierarchy in a typical WCDMA application where the essential calculations are centered around five major signal processing functions include: 1) "chip matched filtering", "code search", "chip demodulation / despreading", channel decoding and symbol rate processing , These algorithmic threads typically require algorithms consisting of millions of operations per second (MOPS). An exemplary spread spectrum application may group these algorithms into five categories based on their MOPs. These groups include: 1) a chip rate processor group, a symbol sequence processor group, 3) a parameter estimation processor group, 4) a channel element (multi-finger) processor group, and 5) an input processor group. A user has the option to bypass a processor group via the bypass mechanism and / or the coprocessor interface. Using the term hierarchical connection, the present invention offers a high degree of flexibility in user definition of the preferred sharing boundaries between hardware and software. In the present embodiment, this limit may actually change over time based on the type, capacity, performance, and computational efficiency of the host computer, such as the processor 120a from 2 , and the configurable communication device, such as the configurable device 104 from 1A ,

The allowed connections in the step 3008 are provided in the design phase of the communication device, based on an assumed flexibility due to protocol changes, possible algorithmic flexibility needs, projected future algorithmic and protocol-related growth, and indefinite postings. In one embodiment, the allowed connections {Ci} for a given configurable device may be static in a memory of the computer 120a to provide. Alternatively, the allowed connections {Ci} for a given configurable device may be determined dynamically by a calling component of a configurable device, such as the communication device 100a , via a coupling arrangement (wireless or serial / bus hardware) by the computer system 120a , The step 3008 controls a set of communication primitives that match those in step 3008 Validated connections correspond to the implementation file output 3007 at. The implementation file 3007 describes how a function is formed from the set of basic data and control structures in the hardware cores. In particular, the step comprises 3008 the formation of an abstraction of the data path configuration by the implementation file output functions 3007 ,

By providing a diagram of these interfaces, for example in a list, state machine or table, the compatibility of data types between sequential functions and hardware implementations can be checked and corrected if necessary. Consequently, the step represents 3008 A quality control procedure is provided for the functions implemented, guaranteeing a level of operational safety and efficiency. By intelligently tracking the interfaces of functions and sub-functions, the computer can keep track of a disordered, user-selected list of functions or sub-functions. The step 3008 In one embodiment, storage of data types in memory of a storage medium, such as the blocks, for example 206 . 208 or 210 of the computer system 120a in 2 , and mapping the interfaces through the processor 204 realized. In the flowchart 3000 follow the step 3008 a step 3010 ,

In step 3010 In the present embodiment, the desired operation is mapped to a function-specific computing element with local control. The step 3010 In one embodiment, this is by the processor 204 Realizes the desired functions and / or sub-functions and operations in the steps 3002 and 3004 which maps to the available hardware resources of a given configurable device.

The imaging step 3010 essentially combines a function with a hardware core with a matching architecture. In particular, configure the in step 3006 selected parameters propagate the hardware kernel for the specific subfunction or operation within a class of possible subfunctions or operations. This scenario occurs for the many different mathematical, computational, and logical categorizations for the different functions used in a given application and the reconfigurability area for which individual hardware cores can be designed.

In an exemplary embodiment, the steps 3002 to 3012 for a class of Despreading and equalization functions are adapted with different parameters that belong to different communication protocols to which they belong. This embodiment provides a hardware core (or computational element) with sufficient reconfigurability that can accommodate the differences in despreading and equalization functions between the protocols. Consequently, the reconfigurability parameters are provided to a user for the desired selection.

The step 3010 controls a set of extensible data types that belong to the hardware cores and their configurable properties to the implementation file output 3007 by appropriate specification of available resources to perform a desired function and / or sub-function. Other input information, other than the available resources, can be used for the step 3010 be considered. For example, the flexibility of a local controller (not shown) of a computing element 106 also for the step 3010 be considered. Particularly complementary is the mapping of desired functions to available resources in a multiprocessor device with specific components for algorithms, since the hardware components (e.g. 106 and 108 from 1A ) are essentially locally controlled, object-oriented devices.

As a short example, applied to the steps 3002 to 3010 , a user selects a modulation function in step 3002 and an integration and memory expression subfunction for the step 3004 out. As a result of this input information, the variation of integration lengths from the set {4, 8, 16, 32, 64, 128, 256} is provided as a possible parameter selection. If the user implements a 3GPP standard, an exemplary parameter selection corresponding to the step 3006 is a 64-bit integration length, as required by the standard for a specific mode of operation. Below is a signal flow path through the step 3010 is provided and the kernel designed for the integration and output class of functions is passed through the step 3008 is mapped to the corresponding parameter settings. While the present example is applied to a specific function and parameter variation, the present invention is well suited to a wide range of applications, functions, and subfunctions. In the flowchart 3000 follow the step 3010 the step 3012 ,

In step 3012 In the present embodiment, a query determines whether additional sub-functions or operations are desired. If no additional functions or sub-functions are desired, the flowchart moves 3000 with the step 3016 continued. However, if additional sub-functions or operations are desired, the flowchart proceeds 3006 with the step 3013 continued. The step 3012 provides the logic to iteratively build the set and types of subfunctions and operations necessary to provide full functionality within the configurable device, for example to establish a modem function within a communication device.

The step 3013 becomes necessary when additional functions or operations in step 3012 are desired. In step 3013 In the present embodiment, a query determines whether time sharing of resources is desired. That is, depending on the desired subfunction or operation and its computational rate requirement, and depending on the computational rate of a given component of a configurable device, the component may have idle times within a system cycle to accommodate additional operations. For example, the computing element 106 from 1A directly from a host processor (not shown) of the configurable communication device 104 be configured to operate in different modes, depending on macroscopic parameters, such as the standard, and microscopic parameters, such as the integration window for a search correlator. Exemplary scheduling of the modem and encode / decode functions (described in appendix A of the co-pending application "A WIRELESS SPREAD SPECTRUM COMMUNICATION PLATFORM USING DYNAMICALLY RECONFIGURABLE LOGIC", incorporated herein by reference) realizes a plurality of transceiver signal paths by configuring the Hardware cores and connections according to the desired types of operations and data flows. In the flowchart 3000 follow the step 3013 the step 3014 ,

In step 3014 In the present embodiment, the time range of resources for multiple uses is divided. The step 3014 is realized by capturing the capabilities of the components in a configurable device, as in step 3013 described. The splitting process can be done using the processor 204 from 2 together with the calculation resource input information 116b from 1B to be realized in the store 206 . 208 or 210 from 2 can be stored. Coming soon, the components 106 and 108 the configurable communication device 104 from 1A are treated as hardware computational resources that can be applied to a single computational process, for example a "multipath" of a given channel in one embodiment. However, in the present embodiment, the computational resource provided by the example components may be the same 106 and 108 of the configurable communication device 104 can be improved by operating at a higher clock rate than that required by a process, for example higher than the data rate for a communication protocol. In this way, resources of individual computational components, such as a configurable demodulator, may be nested (or split) in time between multiple computational processes, for example, some "multipath" and / or multiple channels. Configuration and state data for each of the temporally nested resources of the configurable device is given by the flowchart 3000 made available. Additional information about designing and implementing configurations of a configurable communication device is provided in co-pending U.S. Patent Application Serial No. 09 / 492,634, entitled "IMPROVED APPARATUS AND METHOD FOR MULTITHREADED SIGNAL PROCESSING" by Ravi Subramanian et al., Attorney Docket Number MORP- P002 provided. This related application is filed jointly and is hereby incorporated by reference. Following the step 3014 the flowchart returns 3000 to the steps 3006 to 3010 back in which the temporally nested resource can be inserted into the signal flow path and the mapping operation.

The step 3016 becomes necessary if no additional functions or operations in step 3012 are desired. The step 3016 is responsible for the condition in which a desired configuration for a configurable device for current implementations on the configurable device is essentially determined by the following steps. In step 3016 In the present embodiment, a configuration for the configurable connection unit is generated to perform the mapping step 3010 to fulfill. Hence, the step is 3016 responsible for all the individual input / output data lines (not shown) of the hardware cores, for example the computing element 106 respectively. 108 from 1A ,

The step 3016 also maps the boundaries within the reconfigurable connection unit, which in one embodiment has limited connectivity between all the different configurable hardware cores. In one embodiment, the step generates 3016 a set of rules that sets up the configuration of the configurable connection unit with digital instructions that turn on electronic devices of the connection unit, such as transistors, and thus make the appropriate connections. The step 3016 In one embodiment, it is implemented by storing the configuration or set of rules in memory to which the reconfigurable connection unit has access. However, the present invention is well suited to the step 3016 using alternative storage techniques. Furthermore, when hardware core resources are time-nested, more than one set of configurable connection unit or configuration rules may exist, and thus become reconfigurable between the multiple sets of rules. The periodicity of the configuration of a configurable connection unit may include a wide range, for example, from milliseconds to months, depending on the application. In the flowchart 3000 follow the step 3016 the step 3018 , In step 3018 In the present embodiment, a temporal order is defined for the configuration of the configurable connection unit and for the hardware cores. In step 3018 In the present embodiment, input information is received from a computer identifying a desired function that the configurable device is to perform. The step 3018 In one embodiment, it is implemented by a user entering data via the optional input device 216 or from the storage medium 206 . 208 or 210 of the computer system 120a in 2 provides. A user can enter any desired function in a programming aid, such as the function library 116a from 1B is included. However, the present invention is well suited for any types of functions as provided in the configurable device.

The in step 3018 desired function may be a higher function, for example, a modulation that can be further divided into more discrete sub-functions. The step 3018 For example, a list of these subfunctions or operations may be provided to the user via a graphical user interface (GUI) for use in subsequent steps of the flowchart 3000 provide. In the present embodiment, the list of functions establishes a one-to-one association with the computing elements, such as the computing elements 106 and 108 from 1A , and is consequently limited by these. The present invention is well suited to the step 3018 to realize with different degrees of functional granularity. In particular, the configuration designed for the configurable architecture is scalable for data rates due to the locally controlled, autonomous hardware cores. This means that increasing the clock rate is the speed of the whole communication device, for example 100a . can increase. In the flowchart 3000 follow the step 3018 the step 3020 ,

In step 3020 In the present embodiment, the downloaded configuration is distributed to the plurality of computing elements. The step 3020 is used to distribute configuration data for a time-shared hardware core resource whose configuration is changing. For example, two communication channels may require different configurations of integration and memory output functions, for example IS-95 for one channel and CDMA 2000 for another channel, or Japanese ARIE WCDMA and ETSI 3GPP WCDMA, which are concurrently operated in a base station. For a given function-specific kernel that supports the despread function, the configuration for the corresponding channel must change. The change in configuration depends on the frequency of access to the despread function, for example, the frequency may occur at a multiple of the chip clock rate, a chip clock rate, or any period appropriate to the application. In this scenario, the hardware core is reconfigurable on a very efficient basis. Note that if the given function-specific kernel is time-shared, but uses the same configuration, for example, both channels use IS-95, then no different configuration needs to be distributed for the switch. A final output information of the flowchart 3000 represents the configuration picture 118a , the timing 118b , the connection configuration 118c and clock rates 118d to disposal. The flowchart 3000 ends after the step 3020 ,

An example of a computer program showing the flowchart 3000 realized for a desired function, referred to as a finger, is shown in Appendix B of the co-pending application "A WIRELESS SPREAD SPECTRUM COMMUNICATION PLATFORM USING DYNAMICALLY RECONFIGURABLE LOGIC", which is incorporated herein by reference. A user defines the finger function through an implementation file, such as the file 3007 by definition: the sequence of operations, the parameters that control the flow of data, and the parameters that control the initiation and termination of the function. Thus, a specific finger behavior is subsequently realized by forming the finger using the principle of an expandable data type. The sequence of operations defining a finger are determined by the user and then declared as the finger type. The user then declares the parameters that control the data flow and then defines the initiation and completion conditions. It is assumed that one skilled in the art can interpret the computer-language-specific syntax used in this example. This example shows how the user can achieve a specific level of control over the functions performed on the hardware cores. Thus, controllability, observability, and new configurations and behaviors may be realized through the use of the extensible data types of the present invention. As a result, the present invention overcomes the limitations associated with conventional configurations.
