Development of Image Processing System Based on DSP and FPGA

Real-time image processing system is widely used in many field, it is required to have high speed. In order to satisfy the demand, an image processing system structure based on DSP and FPFA is presented, that is DSP is used as advanced image processing unit and FPGA as logic unit for image sampling and display. The hardware configuration and working principle is introduced firstly, and then some key problems which include of image data stored mode, color space conversion and image transmission based on EDMA are described. Finally the program flowchart for developing image processing software is given. The developed system can acquire image, display image and make some image processing operations which include of geometry transform, orthographic transform, operations based on pixels, image compression and color space conversion. The developed system can meet the real-time requirement and has been used in our teaching.
