Abstract

The high computational demands of modern multimedia applications such as the H.264 video coding standard pose serious challenges on current hardware architectures. A natural way to tackle this problem is the use of multi-core systems. In this work, we introduce a high-level simulator, the Partition Assessment Tool. This tool supports the development of efficient and application-optimized multi-core video coding systems.

An application of the Partition Assessment Tool is demonstrated. We introduce a new multi-processor multimedia chip called SVENm. This programmable architecture targets multimedia applications with a special focus on video encoding and decoding. A description of SVENm´s architecture is provided. We give insights on how the Partition Assessment Tool is used to find an optimized multi-core partitioning of an H.264 video decoder on the SVENm architecture. This partitioning is optimized in terms of computational complexity, software parallelization and displaying.
