Abstract

There has recently been much interest in stream processing, both in industry (Cell, Storm series, NVIDIA G80, AMD FIRESTREAM) and academia (IMAGINE). Some researchers have accelerated a lot of applications in media processing, scientific computing and signal processing with a special programming style called stream programming. This paper presents a framework to program DSP with this special programming style. Stream program can run on DSP without any architectural support. H264 encoding is selected to evaluate our technique. The result shows that significant speedup is achieved, ranging from 3.2x for cavlc up to 7.1x for analysis.
