Abstract: An embedded system based on FPGA has been developed and its associated aspects such as interface protocol, port matching, software and hardware construction is investigated. System construction is designed according to functional requirement, and the design method for each functional module of the system is presented. Then signals of interface module, image data storage and process module have been programmed and simulated. Experimental results indicate processed and displayed by designed system. It can satisfy the system requirements of lower cost, saving space, improving systems tability and work bandwidth.
