Abstract(in English) | In past time, the research that Viterbi decoder is achieved on VLSI was studied, but it was unique research that Viterbi decoder has changed constraint length or any other decode conditions. Using FPGA (Field Programmable Gate Array) and CPLD (Complex Programmable Logic Device) which are traditional reprogrammable not need to prepare more decoding circuits, but there was a failure that it takes a long time to reconfigure the circuit. In this paper, we used Reconfigurable Processor DAPDNA-II and we had implemented Viterbi decoder among four constraint length from 3 to 6. In this paper, using BER and performed the simulation of changing constraint length. In the result, when the throughput was fixed on 6.40Mbps, and the reconfiguration of circuit was performing frequently, it is compared with constraint length of the best performance, we had confirmed the reduction of power consumption about 40%-80%. |
