摘要
提出了一种基于Nios Ⅱ软核处理器的嵌入式图像采集处理系统架构,在图像采集缓存区、图像处理缓存区和图像显示缓冲区之间通过Avalon总线流模式管道实现了数据的高速传输,着重介绍了该系统中组件模块的定制与设计,并给出了该系统的一个应用实例。
An embedded system architecture for image acquisition and processing, based on a Nios II soft-core processor, is presented in this paper, where high speed data transmissions among image acquisition buffer, image processing buffer and image display buffer are implemented with Avalon-bus streaming interfaces. Emphatically, custom and design of main composition modules for the system are described, and an example for using the system is given.
