摘要：由于专用指令集处理器（ASIP）具备ASIC的高效性与通用处理器的灵活性，在视频处理领域有着广阔的应用前景。设计了一种面向视频应用的SIMD处理器，它包括显式数据置换的专用指令集和专门设计的数据通路和运算单元，实现了高效的视频处理。并采用SMIC 0.18 μm标准CMOS工艺对该设计进行了VLSI实现，在最差工作条件下，时钟频率可达到180 MHz，面积约12.38 mm2。表明该处理器能极大地提高视频处理的效率。

Abstract: The ASIP, which features the high efficiency of ASIC and the flexibility of General Purpose Processor, has and will have been popular in video processing domain. A new design of SIMD proccessor, which had an explicit data organization instruction set and special hardware architecture, was presented. The design was synthesised in SIMC 0.18 μm standard CMOS technology, with a frequency of 180 MHz and an area of 12.38 mm2 under the worst working condition. The results show that the processor can improve the efficiency of video processing greatly.
Key words: application specific instruction set processor(ASIP); video processing; single instruction multiple datu(SIMD); explicit data organization; pipeline; very large scale integration(VLSI)
