A Viterbi decoder aimed at a low power implementation has been studied. Viterbi decoders are used for decoding convolutional forward error correction codes in a large proportion of digital transmission systems including mobile phones and digital television. The path metric unit (PMU) is the core of the Viterbi decoder. The asynchronous Viterbi decoder comprises a branch metric unit (BHU), PMU and a history unit (HU).
