Tensilica’s Dolby Digital AC-3 Decoder Application Package
The Dolby Digital AC-3 Decoder package for the Xtensa HiFi Audio DSPs implements the Dolby Digital (AC-3) audio decoder supporting multichannel (5.1) and stereo decoding over the full range of bit and sample rates. The decoder is a fixed-point implementation written fully in C and available in object code. Included documentation describes how to incorporate the decoder into a system. Using this package, system developers can integrate an AC-3 decoder into an SOC without the need for additional optimizations or software development. The same Xtensa HiFi Audio DSPs are used for other Tensilica audio codecs, enabling the development of highly optimized multi-standard audio SOC designs.
