关键词	This paper presents real-time MPEG-4 Simple Profile video compressing based on the DSP processor. The programming framework of video compressing is constructed using TMS320C6416 Microprocessor the architecture level optimizations are used to improve software pipeline. The system used DSP/BIOS to realize multi-thread scheduling. The whole system realizes high speed transition of a great deal of data. Experimental results show the encoder can realize real-time encoding of 768*576 TDS510 simulator and PC. It uses embedded real-time operating system DSP/BIOS and the API functions to build periodic function 25 frame/s video images. 2009 Copyright SPIE - The International Society for Optical Engineering. tasks and interruptions etcs. Realize real-time video compressing. To the questions of data transferring among the system. Based on the architecture of the C64x DSP utilized double buffer switched and EDMA data transfer controller to transit data from external memory to internal and realize data transition and processing at the same time
