Abstract :
Different architectural approaches for saving energy are considered for the ACS unit of a Viterbi decoder. It was found that although providing less throughput improvement than parallelism, pipelining is more energy efficient. The optimal mix of these two architectures favors more pipelining at lower throughput requirements
