ABSTRACT:
A path metric computing method applied in a high-speed Viterbi detector and related apparatus thereof are disclosed. The path metric computing apparatus includes a comparator for generating a control signal according a plurality of previous path metrics, a combining circuit for generating a plurality of first output values according to the previous path metrics and branch costs of a plurality of branches of a current state, and a multiplexer, electrically connected to the comparator and the combining circuit, for determining a first path metric of the current state according to the control signal and the output values.
