Abstract: Method and apparatus for process accelerator (PA) using configurable hardware accelerators is provided. The PA can include a plurality of processing elements (PEs). The PEs of the PA can be used to accelerate a process and/or one or more threads. PEs can include PE local memory which due to the memories' close physical proximity to the PE can result in reduced energy consumption. The plurality of PEs can be daisy-chain connected or DMA mode can be used to write the result of a PE directly into the PE local memory of another PE for further processing.

Abstract: The disclosed structures and methods are directed to decoders and to methods for decoding codes, for example, polar codes. The decoder comprises: a codeword node decoding pipeline having three logic units, and configured to, for each encoded codeword node: based on a received instruction sequence, adjust the three logic units for decoding of each encoded codeword node, and decode a set of logarithmic likelihood ratios (LLRs) corresponding to the encoded codeword node to generate decoded bits. The decoder also has an output storage configured to store the decoded bits corresponding to each encoded codeword node, and generate a decoded codeword based on the decoded bits. The decoding method comprises adjusting the codeword node decoding pipeline to each encoded codeword node based on codeword node length and a codeword node type, as well as a bit index of the encoded codeword node.

Abstract: The method can be performed in a processor integrated circuit having an instruction decoder and a plurality of shared resources, a resource tracker circuit having a plurality of credit units associated with corresponding ones of the shared resources in a manner to be updatable based on availability of the shared resources, and a resource matcher connected to receive a resource requirement signal from the decoder and connected to receive a resource availability signal from the resource tracker. The method can include performing a determination of whether or not the resource requirement signal matches the resource availability signal, and, upon a positive determination, dispatching corresponding instruction data, updating the status of a corresponding one or more of the credit units, and preventing the resource matcher from performing a subsequent determination for a given period of time after the positive determination.

Abstract: The embodiments employ a transaction based design methodology to supply clocking when clock pulses are requested. The transactional module receives a clock when it requests a clock pulse and one stage of a logic pipeline is clocked at a time. This methodology reduces dynamic power dissipation by the transactional module from the dynamic power dissipated by traditional synchronous logic designs.
