Hardware accelerating audio coding algorithms

This paper evaluates hybrid hardware-software structures for acceleration and power savings in Audio Coding Algorithms. Using the well known MPEG I/II Layer 3 (mp3) decoder as example, we will demonstrate the general principles and trade-offs. The results, obtained for mp3, are valid for (but not limited to) the full family of MPEG Codecs, due to algorithmic similarities, including AAC and HE-AAC.
