Abstract
Efficient software implementations of the Viterbi algorithm on two new generation processors, /spl mu/PD7701x and V830 are discussed. /spl mu/PD7701x is a 16-bit fixed point general purpose DSP which includes eight 40-bit general purpose registers, highly parallel operation capability, and conditional execution capability. V830 is a 32-bit RISC processor which has a multiply-accumulator and other special instructions for multimedia signal processing. These features enable effective implementations on both processors. The Viterbi decoders for rate 1/2 convolutional code are implemented on these processors and are two times faster than on conventional type DSPs.
