摘　　要：设计一种以DSP为核心,FPGA协助数据采集、传输的图像处理平台。DSP运行复杂图像处理算法,通过EMIF接口和FPGA进行高速数据传输。FPGA对EMIF接口进行扩展,将图像传感器、SDRAM存储器、USB接口等统一到EMIF接口,提高系统的集成度和灵活性,实现DSP与FPGA、外设之间数据准确、高效、可靠的传输。实验表明,该系统满足实时性设计需求,易于扩展和升级,具备较强的通用性。An image processing platform with digital signal processor （DSP） as a key part and field-programmable gate array （FPGA） as an auxiliary part for data acquisition and transmission is designed. Complex image processing algorithms are operated in DSP and data are transmitted at high speed via external memory interface （EMIF） and FPGA. EMIF is expanded to integrate image sensors, synchronous dynamic random access memory （SDRAM） and USB interface with EMIF so as to enhance the integration and flexibility of the system. And accuracy, high efficient and reliable data transmission between DSP and FPGA as well as external equipments is realized. Experiments show that the real time design requirements are met and the system has higher universality and easy to be expanded and upgraded.
