  • Abstract
    An LSI ADPCM codec, which is based on the CCITT standard 32 kbps algorithm, has been developed. The LSI chip has been designed as a software controllable signal processor whose architecture is optimized for the CCITT algorithm. A reconfigurable pipeline multiplier-normalizer-accumulator circuit is effectively utilized for realizing complex ADPCM specifications. The LSI chip, implemented by 2.5 µ CMOS technology, dissipates only 90 milliwatts of power.
