Abstract :
A multi-wire error correction scheme, which combines Hamming product codes with type-II hybrid ARQ, is proposed for reliable and energy efficient SoC links. Also, a hard decision iterative decoding method, which can achieve the maximum error correction capability of Hamming product codes, is proposed. Simulation results show an improvement of up to four orders of magnitude in residual flit-error rate for multi-wire errors. For a given system reliability requirement, the proposed error control scheme can achieve 35% energy improvement over other error correction codes.
