Abstract
This invention concerns a novel Viterbi decoding apparatus and method in which a survivor path unit (SPU) implements the traceback method with a RAM which stores path information in a manner which allows fast read access without requiring physical partitioning of the RAM. This results in an implementation that requires less chip area than conventional solutions.
