High-Performance Implementation of Stream Model Based H.264 Video Coding on Parallel Processors

Model-based design is widely accepted in developing parallel program. Stream model, an emerging model-based programming method, shows surprisingly good efficiency in many compute-intensive domains, especially for complex media processing. On the basis, this paper illustrates how to map the stream H.264 encoder onto concrete parallel processors such as stream processor. Results show that our encoder achieves significant speedup over the original X264 encoder on various programmable architectures.
