The Hardware Design on the System of High-Speed Image Gathering Based on FPGA and DSP

On the foundation of analyzing in an all-round way to the current application situations and development trends with image acquisition and treatment technology on domestic and international, the paper designed one system that aim at the problems including high-speed rate of analog-to-digital conversion, heavy amount data and complicated arithmetic and so on that existing in high-speed image acquisition board and realize the high-speed acquisition and processing of image. The key part of the system is DSP and programmable arrays device FPGA, The main circuit including the standard video signal separation circuit, A/D converter circuit, phase locking multiple frequency circuits and the DSP, such as power supply circuit, etc. The circuit is simple, dependability, and have certain common ability.
