Low power state-parallel relaxed adaptive viterbi decoder design and implementation

In this paper, we present an algorithm/architecture.. level design solution for implementing state-parallel adaptive Viterbi decoders that, compared with their Viterbi counterparts, can achieve significant power savings and modest silicon area reduction, while maintaining almost the same decoding performance and throughput. The effectiveness of the proposed solution has been demonstrated using convolutional codes decoders as test vehicles, where Synopsys tools are used for synthesis, layout, and post-layout power estimation(1).
