DVI核心技术剖析与逻辑实现

Logical Analysis and Realization of DVI Key Technique

数字视频接口规范为独立显示的视频数据提供了一个高速数字链接,其核心技术是传输最小化差分信号(TMDS)。文章分析了TMDS的架构和设计原理,详细阐述了TMDS软核的设计方法,采用自顶向下(Top-Down)的设计方法和流程图模式,设计出具有自主知识产权的、可灵活移植的TMDS接收器和发送器(IP软核),并通过FPGA实现验证。该IP软核不仅可以应用于专用的高分辨率雷达显示,也可以用于一般用途的手持设备。

DVI specification which uses the key technique（TMDS）for the base electrical interconnection provides a high-speed digital connection for visual data types displayed independently.The structure,principium,and design process of TMDS soft-core are introduced.It realized by the Top-Down design structure and flow-chart mode in FPGA,which has self-determination intellectual property and flexibility.The application field of TMDS soft-core is wild,it can be used not only in special high-resolution radar display,but also in ordinary handheld devices.
