摘　　要：针对专用视频处理器TMS320DM8148不能直接采集Cammera Link接口的视频数据的问题,提出一种基于TI方案的编码系统,采用DSP+FPGA构架,FPGA以其优良的逻辑性,负责采集Cammera Link接口的视频数据;FPGA采集视频数据后缓存,然后通过GPMC传送给DM8148;DM8148通过内部各模块相互协作,实现编码。后期测试表明该方案视频显示流畅无误码,证明了该方案的可行性。Aiming at the problem that the TMS320 DM8148 can not collect the video data of Cammera Link interface directly,a kind of coding system based on TI scheme was proposed.With the DSP ＋FPGA architecture,FPGA is responsible for collecting the video data of Cammera Link interface with its excellent logic. FPGA collects and caches the video data which are sent to the DM8148 through the GPMC; DM8148 cooperates with each other through the internal modules to achieve coding. The later tests show that the scheme is smooth and error free,proving the feasibility of the scheme.
