    Abstract

    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.
