Abstract
This paper describes a novel video specific instruction set architecture for ASIP design. With SIMD (Single Instruction Multiple Data) instructions, and video specific instructions, an instruction set architecture is introduced to enhance the performance for video applications. Furthermore, we quantify the improvement on H.263 encoding. In this paper, we evaluate and compare the performance of VS ISA (Video Specific Instruction Set Architecture), other DSPs (digital signal processors) and conventional SIMD media extensions in the context of video coding. Our evaluation results show that VS ISA improves the processors performance by approximate 5x on H.263 encoding, and VS ISA outperforms other architectures by 1.6x to 8.57x in computing IDCT.
