【摘要】 针对高分辨率雷达图像显示的应用,利用Altera公司提供的片上系统开发工具设计了一个基于Nios Ⅱ软核处理器和高清多媒体接口(HDMI)芯片的图像显示系统;可将并行输入的灰度图像信号转换成CEA-861-D建议规定的多种视频格式,在HDMI(DVI)显示器上滚动输出图像,分辨率最高可达1920x1080p@60Hz;通过软硬件协同设计的方法提高系统的灵活性和可扩展性。更多还原

【Abstract】 A high definition display card which is based on Altera’s Nios Ⅱ processor and high definition multimedia interface(HDMI) is implemented for radar systems.The card is able to transform parallel gray-scale image data into various video formats specified by CEA-861-D recommendation,and then display it on a LCD with HDMI or DVI interface.The highest resolution reaches 1920x1080p@60Hz.With the method of hardware and software co-design method,the flexibility of system is improved.更多还原
