Description
Summary:This paper investigates the algorithmic complexity of arithmetic coding in the new H264 video coding standard and proposes a processor-coprocessor architecture to reduce it by more than an order of magnitude. The proposed coprocessor is based on an innovative algorithm known as the MZ-coder and maintains the original coding efficiency via a low-complexity, multiplication-free, non-stalling, fully pipelined architecture. The coprocessor achieves a constant throughput for both coding and decoding processes of 1 symbol per cycle and is designed to be attached to a controlling embedded RISC CPU whose instruction set has been extended with arithmetic coding instructions.
