System-level performance evaluation of a H.264/AVC encoder targeting multiprocessors architectures

The system-level modeling and simulation framework Sesame/Artemis aims to efficiently explore the design space of heterogeneous embedded multimedia architectures. The Sesame environment provides several methods and tools to quickly and separately build the application process network model, the target architecture model, and the mapping model of the application onto the architecture. In addition, this tool is designed to allow the refining simulation models smoothly across different abstraction levels and to include support for refining only parts of an architecture model, creating a mixed-level simulation model. In this paper, the Sesame software framework is selected to implement at the black-box architecture model level a parallel H.264/AVC video encoding application targeting multiprocessors platforms.
