摘要
针对图像处理系统的高速数据采集要求,利用总线切换和乒乓控制的原理,设计了一种基于CPLD芯片与SRAM芯片构成的高速图像数据采集系统。详细论述了系统软硬件设计,并对各种可能出现的异常情况进行了分析。经现场测试和长时间运行,该系统工作稳定,抗干扰能力强,能满足前端图像数据高速实时性要求。
Considering the requirement of high-speed data acquisition for image processing system, we designed a high-speed acquisition interface system based on the CPLD and SRAM chips by using the theory of bus switch and Ping-pong control. The design methods of software and hardware are discussed in detail, and various possible abnormal situations are analyzed. Test on the spot and long-time running proved that the system is stable in operation with strong anti-jamming capability, which can satisfy the high-speed, realtime requirement of preceding image data.
