Design of digital audio input output chip

Abstract

The design of a digital audio input output (DAIO) chip that interfaces a standard 16/32-bit microprocessor bus with audio devices based on the AES protocol is described. This novel design provides general-purpose microprocessor systems with the ability to communicate with compact-disk and digital-audio-tape players. The chip is designed, using high-level and logic synthesis tools, from a function description in a hardware description language
