Implementation of A Real-Time Digital Image Processing System Based on FPGA and DSP

In this paper, in order to satisfy the real_time requirements of the picture correlation processing when the CCD correlation tracker tracks image signal in the observation from satellites to the earth, the fast algorithm of the picture correlation processing technique is discussed, while its kernel module_FFT function is implemented by FPGA to increase the working speed. On the basis of this, a real_time digital image processing system based on FPGA and DSP is designed. At the same time, the design of hardware and software arithmetic of this system is presented respectively. The result of simulation and experiment proves that the combination of FPGA and high_speed digital signal processing algorithm can meet the real_time requirements of picture correlation processing in the CCD correlation tracker.
