Tensilica FLAC Decoder for the Xtensa HiFi Audio DSP

Tensilica’s HiFi Audio DSP family of IP (intellectual property) cores for SOC (system-on-chip) design now features the Free Lossless Audio Codec (FLAC) decoder. FLAC is an audio format similar to MP3, but lossless so the audio is compressed without any loss in quality. It is not a proprietary format. As a result, FLAC is not encumbered by patents, and has an open-source reference implementation. Tensilica’s FLAC decoder supports both stereo and multi-channel formats.
