An MSB-First 1-of-N Single-Track Asynchronous Add-Compare-Select Unit for Viterbi Decoders
In this paper, a new Add-Compare-Select unit for Viterbi decoder is presented. By implementing carry-save addition and most-significant-bit-first (MSB-First) comparison with 1-of-N asynchronous single track template, the computation speed can vary with different input data patterns, and thus performance improves considerably. A comparison between different circuit styles is also provided, which shows the performance of our design is potentially better than other designs.
