    摘要: The present invention discloses a single unified decoder for performing both convolutional decoding and turbo decoding in the one architecture. The unified decoder can be partitioned dynamically to perform required decoding operations on varying numbers of data streams at different throughput rates. It also supports simultaneous decoding of voice (convolutional decoding) and data (turbo decoding) streams. This invention forms the basis of a decoder that can decode all of the standards for TDMA, IS-95, GSM, GPRS, EDGE, UMTS, and CDMA2000. Processors are stacked together and interconnected so that they can perform separately as separate decoders or in harmony as a single high speed decoder. The unified decoder architecture can support multiple data streams and multiple voice streams simultaneously. Furthermore, the decoder can be dynamically partitioned as required to decode voice streams for different standards.

    摘要: A memory is partitioned into rows and columns of memory blocks comprised of latches, sense amplifiers, and logic circuitry that form independent pipelines through which flow a) input addresses for memory access requests and b) data to be written into a specific memory cell within a memory block. The memory allows multiple data access requests in consecutive clock cycles to be pipelined in the rows and columns of memory blocks such that the memory clock speed is equal to the clock speed of a single memory block, independently of the memory size.

    摘要: Improved operation of multi-processor chips is achieved by dynamically controlling processing load of chips and controlling, significantly greater than on/off granularity, the operating voltages of those chips so as to minimize overall power consumption. A controller in a multi-processor chip allocates tasks to the individual processors to equalize processing load among the chips, then the controller lowers the clock frequency on the chip to as low a level as possible while assuring proper operation, and finally reduces the supply voltage. Further improvement is possible by controlling the supply voltage of individual processing elements within the multi-processor chip, as well as controlling the supply voltage of other elements in the system within which the multi-processor chip operates.
