摘要
基于目前视频监控系统的现状,提出了一个基于SOPC的视频监控系统。系统以NIOS II软核作为嵌入式系统核心、自定义用户外设和用户指令为接口电路I、ME 6400及BT835为外围电路,并采用DMA传输视频监控数据以及UART传输摄像头控制指令。.该嵌入式视频监控系统构建灵活、占用资源少、系统效率高,有较高的可靠性和安全性。
According to current development of video monitoring system, a video monitoring system based on System on a Programmable Chip （SOPC） was presented. NIOS Ⅱ soft-core is suggested as the kernel of embedded system, custom peripheral and custom instruction are defined as interface circuit, and intergrated chips-IME6400 and BT835 are proposed as peripheral circuit. Besides, DMA and UART are used to transferre the vedio monitoring data and contral instructions. This embedded video monitoring system is simple, efficient, reliable, stable, and easy to establish.
