摘要:
A method and an apparatus for configuration of multiple context processing elements (MCPEs)are described. According to one aspect of the invention, the structure that joins the MCPE cores into a complete array in one embodiment is actually a set of several mesh-like interconnect structures. Each interconnect structure forms a network, and each network is independent in that it uses different paths, but the networks join at MCPE input switches. The network structure of one embodiment of the present invention is comprised of a local area broadcast network (level 1), a switched interconnect network (level 2), a shared bus network (level 3), and a broadcast network. In one embodiment, the level 3 network is used to carry configuration data for the MCPEs while the broadcast network is used to carry configuration data for the level 3 network drivers and switches. In one embodiment, the level 3 network is bidirectional and dynamically routable.

A method and an apparatus for retiming in a network of multiple context processing elements in a network of multiple context processing elements are provided. A programmable delay element is configured to programmably delay signals between a number of multiple context processing elements of an array without requiring a multiple context processing element to implement the delay. The output of a first multiple context processing element is coupled to a first multiplexer and to the input of a number of serially connected delay registers. The output of each of the serially connected registers is coupled to the input of a second multiplexer. The output of the second multiplexer is coupled to the input of the first multiplexer, and the output of the first multiplexer is coupled to a second multiple context processing element. The first and second multiplexers are provided with at least one set of data representative of at least one configuration memory context of a multiple context processing element. The first and second multiplexers are controlled to select one of a number of delay durations in response to the received set of data. A delay is programmed in the network structure in response to a data type being transferred between particular multiple context processing elements.

A method and an apparatus for position independent reconfiguration in a network of multiple context processing elements are provided. Wach multiple context processing element in a networked array of multiple context processing elements has an assigned physical identification. Virtual identifications may also be assigned to a number of the multiple context processing elements. Data is transmitted to at least one of the multiple context processing elements of the array, the data comprising control data, configuration data, an address mask, and a destination identification. The transmitted address mask is applied to either the physical or virtual identification and to a destination identification. The masked physical or virtual identification is compared to the masked destination identification. When the masked physical or virtual identification of a multiple context processing element matches the masked destination identification, at least one of the number of multiple context processing elements are manipulated in response to the transmitted data. Manipulation comprises programming a multiple context processing element with at least one configuration memory context and selecting a configuration memory context to control the functioning of the multiple context processing element.
摘要:
An integrated dynamically programmable gate array comprises a two dimensional array of programmable gates. These gates can be implemented as look up tables but hardwired gates with programmable interconnections are also possible. Each one of the gates receives plural input logic signals from plural other gates. Consequently, a broad range of logic combinations are possible. The gates further include locally stored multiple contexts dictating different combinatorial logic operations performed by the gates. The contexts increase the logic operations performable by the gate and the fact that the contexts are locally stored enables better integration and speed. Only a context instruction needs to be distributed among programmable gates. A context signal generator is included that generates a context signal indicating a change in an active one of the contexts. This active context dictates the logic operations of the gates that commonly receive by the signal. Since the contexts information is stored on the gate array, and specifically locally, the context signal can change as fast as every clock cycle of the programmable gate array. To increase functionality, context memory arrays, which store context programming information, are separately addressable so that a new truth table is storable in a first one of the context memory arrays while a truth table of a second one of the context memory arrays is dictating the logic operations performed by the gates. As a result, the functionality of each programmable gate can be increased by increasing the number of available functions for that programmable gate.
摘要:
A processor within a wireless terminal performs data compression, decompression and error correction according to a data compression protocol such as the V.42bis data compression protocol used within GSM wireless networks. This processor includes an interface that receives incoming information or data to be compressed or decompressed according to the data compression protocol. A processing module within the processor is operably coupled to the interface to receive and process the incoming information. Instructions executed within the processing module will divide the processing responsibilities between the processing module and a data compression/decompression accelerator operably coupled to the processing module. Compute intensive operations may be offloaded from the processing module onto the data compression/decompression accelerator to improve overall system efficiency.
摘要:
A method and apparatus for providing local control of processing elements in a network of multiple context processing elements (MCPEs). A MCPE stores configuration memory contexts and maintains data of a current configuration. State information is received from at least one other MCPE. A configuration control signal is generated in response to the state information and current configuration data. A MCPE is selected in response to the configuration control signal to control the MCPE. Each MCPE in the networked array has an assigned physical and virtual identification. Data comprising control data, configuration data, an address mask, and a destination identification is transmitted to a MCPE. The transmitted address mask is applied to either a physical or a virtual identification, and to a destination identification. The masked physical or virtual identification is compared to the masked destination identification. When the masked physical or virtual identification matches the masked destination identification, a MCPE is manipulated in response to the transmitted data by selecting one of a number of configuration memory contexts to control the functioning of the MCPE.

A method and apparatus for providing local control of processing elements in a network of multiple context processing element are provided. A multiple context processing element is configured to store a number of configuration memory contexts. This multiple context processing element maintains data of a current configuration. State information is received from at least one other multiple context processing element. At least one configuration control signal is generated in responses to the state information and the data of a current configuration.
