ABSTRACT:
A digital signal processor includes an execution unit separated into an arithmetic unit, a multiplier unit, a logic unit, a shift unit and a log unit, to implement CCITT G721 ADPCM algorithm with a relatively small size, which reduces the system cost. Also, since the digital signal processor primarily takes into consideration of low power consumption, it is applicable to a mobile communication system. Also, the digital signal processor is capable of implementing easily other ADPCM rates and algorithms as well as the ADPCM algorithm by modifying only the program of an instruction ROM.
