基于CPLD的机载图像处理系统时序设计

Timing Design of the Built-in Video Equipment Based on CPLD

以PAL制视频信号为基础,分析了机载图像处理系统各模块的控制时序特点,基于Xilinx公司的可编程逻辑器件CPLD95108设计了系统主要模块的时序,给出了时序仿真结果.结果表明所设计的时序控制完全满足系统的要求,不仅完成了专用视频器件初始化的控制时序,而且对图像数据的采集、处理、搬移、输出进行了畅通无阻地传递.

Based on the PAL pattern video signal system, the time scheduling properties of each module of an airborne image process system were studied. The time scheduling of the primary modules was realized by the PLD chip of CPLD95108 and simulation was done. The results indicated that the designed time scheduling fully satisfies the requirement.
