摘要
红外视频数字处理技术有广泛的应用,红外高速数据通道是红外视频数字处理系统的核心,此红外视频数字处理系统主要是由红外视频同步,先进先出缓冲区和PCI桥组成.在本文中提出了三层逻辑描述的架构和红外视频数字处理系统数据通道的设计,同时提出了关键逻辑,例如用HDL(硬件描述语言)描述了红外视频同步和PCI局部总线存取.
Infrared video digital processing techniques, in the nonlinear correction FPA process, and infrared signal sampling, FIFO PCI local bus access and even image display and storage have a wide range of applications. Infrared high-speed data channel is the heart of the system of infrared video digital processing, it is mainly composed of infrared video synchronization, FIFO buffer and PCI bridge components. In this paper we put forward a logical description of the three-tier structure and infrared video data channel digital processing system design. At the same time, we told a key logic, for example, HDL （ Hardware Description Language） was used to descript the infrared video synchronization and PCI local bus access. High -speed data access technology has high-speed, reliability and hardware updates easy. It will have important significance by SoC （ system-on-chip） in the designing of complex digital systems.
