摘要
构建了一个基于FPGA的图像存储与回放系统,该系统能够记录红外热像仪输出的数字视频信号,回放时以原格式输出,同时还输出标准PAL格式的电视信号。介绍系统硬件设计及FPGA内部各模块的逻辑功能,并论述设计中的几个关键点。
An image storage and playback system based on FPGA is designed in this paper. The system is used to record digital video signals from thermal infrared imager, the signals are outputed in the original way, and meanwhile the PAL TV signals are also outputed when the system is played back.In this paper the system hardware design and logic function distri- bution of modules in FPGA are presented briefly, and several key points are discussed in detail.
