摘要
针对目前嵌入式智能图像处理系统中的图像数据的传输问题与多DSP、多FPGA间的并行问题,提出并设计了以DSP+FPGA为系统核心,通过TMS320C6455 DSP外设接口进行扩展的嵌入式智能图像处理系统,能够实现图像的实时采集、解析及处理功能;同时开发了基于TMS320C6455 DSP的千兆以太网数据传送接口和高速串行接口,实现了图像处理的网络化和并行化。最后对以太网的数据传输进行了测试,测试结果表明,开发的以太网数据传送接口达到了千兆以太网的要求。
To solve the image data transmission problem of the embedded image processing system and parallel problem be- tween multi-DSP and multi-FPGA, the embedded intelligent image processing system is proposed and designed, which takes DSP＋FPGA as its core, and is extended through TMS320C6455 DSP peripheral interface. The system can realize the functions of image real-time acquisition, analysis and processing. The gigabit Ethernet data transmission interface and high-speed serial in- terface based on DSP TMS320C6455 were designed to implement the networked and parallel image processing. The data trans- mission of Ethernet was tested. The test results show that the Ethernet data transmission interface reached the requirement of gigabit Ethernet.
