This thesis mainly introduces a certain kind of real kernel based on TMS320 DSP- DSP/BIOS. There is an expatiation of the DSP/BIOS startup sequence and the design of a video - tracking system based on the characteristic of DSP/BIOS structure. The system is designed and analyzed by the UML technique. By means of scheduling and communicating between one task and another, managing and sending message and managing the muhithread by time-slicer in the process of video-tracking, the video-tracking system can be achieved reasonably. It is proved that the system work stably , the design and the resource are assigned aright and reasonably when the system satisfy the condition of real-time in practice.
