This paper introduced a method which can realize Viterbi encoder based on VHDL. It described the optimum arithmetic of Viterbi encoder and the principle of Viterbi encoder realized by VHDL language. We can design, simu1ate, match and load in MAX+PLUS II integrate exploitation surroundings. This paper presented the top-design circuit of Viterbi encoder . It also presented the simulation results of Viterbi encoder ’s of main parts and the whole circuit. The results showed that the realization of Viterbi encoder based on VHDL is a fast and effective method.
