【摘要】：高清晰度多媒体接口(High-Definition Multimedia Interface,HDMI)显示接口是嵌入式实现的视频采集及处理系统的重要组成部分,并有逐渐成为此类系统的显示端标准接口的趋势。然而在ZYNQ平台中由于没有在芯片中集成HDMI控制器,所以普遍采用模拟视频信号显示,限制了处理效果的展示和人机之间的交互。采用ADI的开源HDMI IP核以及Xilinx提供的相关IP核结合ADI HDMI发送器ADV7511,在ZYNQ平台上以软硬件协同的工作方式设计实现了HDMI显示端。方案分别基于无操作系统和Linux操作系统环境实现,其中无操作系统实现可以被移植用于一些特定场合或供硬件系统测试使用;而在Linux操作系统下,通过结合直接渲染管理器(Direct Rendering Manager,DRM),本方案可以方便Linux系统下该显示系统的移植与集成。
[Abstract]:High-Definition Multimedia Interface. HDMI display interface is an important part of embedded video acquisition and processing system. And gradually become the standard interface of this kind of system. However, because HDMI controller is not integrated into the chip in ZYNQ platform, analog video signal display is widely used. The open source HDMI IP core using ADI and the related IP core provided by Xilinx combined with ADI. HDMI transmitter ADV7511. The HDMI display terminal is designed and implemented on the ZYNQ platform in the mode of hardware and software co-operation. The scheme is based on the environment of no operating system and Linux operating system respectively. No operating system implementation can be transplanted for some specific occasions or for hardware system testing. On the Linux operating system, direct Rendering Manager is combined with a direct rendering manager. This scheme can facilitate the transplantation and integration of the display system under Linux system.
