摘要
研究了一种基于SOPC技术的嵌入式数字图像回放系统的设计方案.该系统通过在FPGA芯片上配置NiosⅡ软核处理器和相关的接口模块来实现其主要硬件电路,并在视频D/A转换芯片AD7123的支持下,结合系统的软件设计,实现了图像的高速D/A转换和回放等功能.由于采用了SOPC和DMA控制技术,该系统具有设计灵活、数据处理速度快和扩展性好等优点.
This paper researches a design method of embedded Digital Image Replay System based on SOPC technology. The system realizes high - speed D/A conversion and replay of image signal, by configuring NiosII soft core CPU and some corresponding interface modules on a PFGA to construct the hardware of the system, and with the support of a video D/A converters IC ADV7123 ,and by combining software programming. As SOPC and DMA technology are used, the system has such advantages as design flexibility, quick data processing speed and good expansibility.
