MPEG encoding on the Raw microprocessor

Abstract

This work investigates the real-world application of MPEG-2 encoding on the Raw microprocessor. Much of the work involves partitioning the problem so that linear speedup can be achieved with respect to both number of Raw tiles and size of the video image being encoded. These speedups are confirmed through the use of real Raw hardware (up to 16 tiles) and the Raw simulator (up to 64 tiles). It will also be shown that processing power can be allocated at runtime, allowing a Raw system of the future to dynamically assign any number of tiles to the encoding task. In the process both the advantages and the limitations of the RAW architecture will be discussed.
