Stream processing is a new trend in computer architecture design which fills the gap between inflexible special-purpose media architectures and programmable architectures with low computational ability for media processing. Stream processors are designed for computationally intensive media applications characterized by high data parallelism and producer-consumer locality with little global data reuse. In this paper, we propose a new stream processor, named MVSP1. This processor is a programmable stream processor based on Imagine [1]. MVSP exploits TLP2, DLP3, SP4 and ILP5 parallelisms inherent in media applications. Full simulator of MVSP has been implemented and several media workloads composed of EEMBC [2] benchmarks have been applied. The simulation results show the performance and functional unit utilization improvements of more than two times in comparison with Imagine processor.
