Abstract
Parallel processing architectures are set to be the dominating design approach for a plethora of application domains, mainly because of the eminent reach of the so-called power wall, and furthermore because of the evident gap between the application/software development growth and Moore''s law. In this work a design space for an audio codec is explored, targeted at a VLIW architecture. The Ogg/Vorbis codec is first analyzed and optimized for exposing potential parallelism to the VEX tools for compilation and parallel architecture exploration. Furthermore, the use of custom instructions is assessed and important results are obtained by means of a modification on the toolchain to reveal dynamic profiling information
