A Real-time Video Processing System Based on FPGA and DSP

A real-time video image processing system is presented.In this system,FPGA is used as a main logic control unit and data buffering,and DSP processes image data.The main architecture of the system is introduced,and several parts are discussed in detail,such as transformation from RGB color dimension to YCbCr,video data buffering,and access to dual port RAM by DSP and FPGA alternatively.And image compressing with DSP is introduced at the end.With the implementation of the system,we can find that the video processing system can work flexible and adaptive with the control of FPGA,which also providse great facility of debugging.
