| 摘 要： | 以数字信号处理（Digital Signal Processing，DSP）平台实现图像处理的应用开发一般较复杂。为加快开发速度和提高程序效率，介绍了专门用于图像应用的DM642开发平台。平台采用DSP／BIOS内核，使用BIOS多线程机制，实现了运动图像的实时处理。与单线程相比，提高了程序执行效率，减少了代码量。DSP／BIOS本质上是一种可剪裁的实时内核，在需要多任务调度和同步的实时应用中，能加快开发，并能达到很好的性能。

| Abstract: | The development of video processing is complex on DSP generally. In order to improve the performance of the application program and reduce the time of development, the DSP/B1OS multi-threading by DSP/BIOS kernel and the TMS320DM642 are introduced. By this method, the system can process the video of missile in real-time, improve the efficiency of program and reduce the code of execution. The DSP/BIOS is a scalable real-time kernel,which is designed for applications that require real-time scheduling and synchronization. The good performance can be obtained in these applications by virtue of the multi-threading mechanism. |
