摘要：
A high speed add-compare-select (ACS) circuit for a Viterbi decoder or a turbo decoder has a lower critical path delay than that achievable using a traditional ACS circuit. According to one embodiment of the invention, the path and branch metrics are split into most-significant and least-significant portions, such portions separately added in order to reduce the propagation delay.
