This paper describes a method to implement the (soft decision output) Viterbi Algorithm in a limited number of instructions and with a minimal modification to the normal hard-ware used in General Pupose Programmable Cores. A relatively low MIPS count and a minimal change to hardware and software to execute the algorithm on a GP core is the objective.
