摘　　要：传统图像采集处理系统多以计算机为平台,其图像处理速度不高,且体积庞大、功耗大。为克服这些缺点,介绍了一种成本低、结构简单、体积小、功耗低的图像采集处理系统。以TI公司的TMS320VC5509A为核心器件,采用大容量FIFO完成视频数据存储,利用CPLD完成逻辑控制功能。软件采用C语言对5509A进行编程,完成整个采集过程的系统调度工作及图像处理算法,增强了易读性和可移植性,提高了图像处理的速度。The traditional image acquisition and processing systems almost depend on computers that process images slowly with big size and high power dissipation.In order to resolve these defects,an image acquisition and processing system is introduced,which has many advanced features such as low cost,simple structure,small size and low power consumption.The system is based on TMS320VC5509A of TI,and adopts large capacity FIFO to complete the storage of video data,and complete the logic control function by CPLD.C language is used to programe for 5509A,that accomplishes the work scheduling of the whole acquisition process.The system enhances the portability and the accessibility greatly,and improves the speed of image processing.
