The logical architecture , protocol , the encoder algorithm , the decoder algorithm and the electronics specification of the tmds which is the core of the dvi and means transition minimized differential signal are described in particular in this paper . and the synchronization and data recovering which mean the central problem in the high speed serial data communications are also analyzed 本文以dvi接口通讯协议为主线,详细介绍和分析了作为接口核心内容的tmds ? ?最小变化差分信号的逻辑架构、通讯协议的编码算法、解码算法、 tmds信号的电气规范等问题,并着重分析了作为高速串行通讯的关键问题的链路时钟同步与数据恢复问题。
Therefore effective tools , for example , an expert system to guide users etc , should be offered . namely when data in hard disk has been destroyed , the software should offers a detailed method for user to complete data recovering breezily , according to causes , categories and appearances of faults 即在硬盘存储器发生问题,数据信息遭到破坏之后,根据发生问题的原因、种类以及发生问题时的表现等实际情况要能给用户提供一个详细的解决方案,用户根据提供的这个方案可以轻松地完成硬盘的数据信息的恢复工作。
