Abstract :
The development of an adaptive vector quantizer (AVQ) codec chip using Open Architecture Silicon Implementation System (OASIS) tools is described. The goal is development of a 16-kb/s AVQ coder prototype system which can be used as an alternative to the currently used 32-kb/s adaptive delta pulse code modulation (ADPCM). The AVQ semicustom chip layout uses 1.2-μm CMOS technology, and consists of 157,191 transistors. The AVQ system is being designed with Mentor Graphics CAD tools and is a four-layer PC board encompassing over 60 analog and digital components
