Variable-length, high-speed asynchronous decoder circuit
Lead Inventors: Steven NowickMethod and system for an asynchronous decoder circuit that operates on data coded using a variable-length coding technique are described. The method and system comprises of an input buffer for receiving input data comprising coded, variable-length data words. An alignment circuit shifts input data by an amount responsive to a control input. A logic circuit coupled to the alignment circuit decodes the coded, variable-length data words. Logic circuit and adder circuit are logically partitioned into multiple computational stages arranged in a computation thread. A completion circuit for produces a completion signal indicating the completion or incompletion of each computational stage.The method and system provides an improved Huffman decoder design that gives a higher ratio of performance to circuit area than is possible with existing circuit designs.
