The Research on DSP Algorithm Implementation Based on CPLD Control of Video Image Processing

摘要

Describes a CCD camera, SAA7111 video decoder chip, high-speed read and write memory, SRAM and CPLD and DSP-based video image acquisition and processing system. System to complete a quick video image capture, storage and data processing. Detail the overall structure of the system, part of the hardware design, and a brief description of the classic image edge detection algorithm and its implementation, the system is given examples and experimental results, the system can be applied to video surveillance and image processing, with good application prospects.
