Based On Tms320dm642 Video Processing System Design

With the rapidly development and widespread application of multimedia technology, people pay more and more attention to video processing technology. Each video processing system has different application fields and functions, so founding a universal video processing platform and doing further development on it according to various requirements has become a significant way of video processing platform design.Since 1990's, the development of the general DSP technology has provided a new method to solve the problem of video processing. TMS320DM642 digital multimedia processor is a 32-bit fixed-point DSP that is developed for multimedia application by TI. It achieves the demand of video processing with their good processing performance and abundant on-chip peripherals. So TMS320DM642 has become one of the perfect platforms for the video processing system currently.Based on the research on DSP technology, this paper discusses how to establish the common video processing platform efficiently, by using RF5 reference framework, encapsulation algorithm and API functions that provide by TI. The advantages of this method are: complicated the bottom layer design avoidance; making full use of eXpressDSP software technology; short developing cycle;...
