Abstract

The emerging digital audio compression technology brings both an opportunity and a new challenge to IC design. High quality multichannel audio is quickly becoming an indispensable part of an entertainment system. The algorithms used in the compression technology result in complex VLSI ICs. The work presented in this paper is about the design of a dedicated, high precision, and low cost AC3/MPEG multi-standard audio decoder. The audio IC´s hardware and software architecture, as well as design and simulation/verification methodology are discussed in detail
