DSP中断，基于定时中断的视频输出与显示。掌握DSP中断原理和DSP定时器工作原理，并能够编写初始化程序，包括中断初始化和定时器初始化。在此基础上完成应用设计(读存储器中的图像，4画面分割，通过定时中断循环在电视监视器上播放)。-DSP interrupt, timer interrupt-based video output and display. Master DSP interrupt the principles and DSP timer works, and be able to write the initialization procedures, including the interrupt initialization and timer initialization. (Read in the image memory based on the application design, 4 split screen playback on the TV monitor by the timer interrupt cycle).
