摘　　要：基于数字信号处理器(DSP)TMS320VC5509A设计并实现图像采集与识别系统.通过CMOS图像传感器采集图像,以DSP作为图像实时处理单元,在CPLD的逻辑控制下,完成采集和识别任务.解决了在DSP提供的地址线少于异步存储器地址线的情况下,实现并行加载的问题.实践证明,该系统具有稳定性、实时性及可编程灵活性.An image sampling and recognition system based on TMS320VC5509A DSP is designed and implemented. In this system, the image sampling unit and processing unit are composed of a CMOS sensor and a DSP, respectively. All logic functions are controlled by CPLD. The parallel booting problem, which occurs when the number of the address lines provided by DSP is less than that of the asynchronous memory, is also solved. Experiment results show the stability, real-time feasibility and programmable flexibility of this system.
