  • Abstract
    A systematic approach for the path metric memory management in Viterbi decoders is presented. Between the parallel computation units and memory modules, a permutation of path metrics is required in order to access the path metrics in correct order. We propose a parallel memory access scheme, which reduces the interconnection complexity between parallel computation units and memory modules by rescheduling the path metric computations.
