Design of high-speed image processing system based on FPGA and DSP

In order to improve the performance of image processing embedded system and reduce its power consumption,a high-efficient image processing embedded system which is based on the field programmable gate array and high-speed digital signal processor(DSP) is presented in this paper.DSP as a main processor is used to control the module of image process,and FPGA chip as a co-processor is used to control the data logic.In the whole system,a novel data transmission structure with a dual-port RAM(CY7C025AV-15AI) is applied to the high-speed real-time image data by ping-pong technique.Because all operation in the system is divided between the FPGA and DSP in the form of the pipelined,the performance of the system is 25% higher than that of the processing system based on the single DSP.The system is easy to transplant other algorithms into it due to its reconfigurability.
