中文摘要：
设计了一种应用于处理器光互连的光接口。该接口基于超传输（HT）协议设计，用光通路替代电通路实现处理器光互连。光接口用原FIT接口逻辑结构，替换原来的输入输出电路的模拟电路部分，增加新的电路结构和光互连通路。该接口为互连接口是源同步结构的处理器应用光互连提供了一种通用的解决方案。整个互连结构兼顾电协议和光信号传输的特点，最大限度保留原接口的工作特点，同时发挥光信号的优势，以最小的代价和较高的效率实现处理器光互连。光接口处于互连的物理层，不需要修改HT接口的应用层，对处理器结构没有影响。
英文摘要：
An optical interface, designed based on the Hyper Transport （HT） protocol for processor optical interconnec- tion, is proposed. HT interface logic It connects processors with optical links instead of original electrical links, and uses the original structure to replace the analogy parts of the IO thus offering a general solution for terface architecture considers both drivers with new digital circuits and optical links, optical interconnection of source synchronized interface processors. The whole in- the electric protocol and optical signal features, and maximizes the operation fea- tures of the original interfaces and the advantages of typical optic signals to achieve processor optical interconnection with the least cost and the higher efficiency. This optical interface is in the physical layer of interconnection, and it need not to modify the application layer of the original HT interface. This does not bring any influence on the pro- cessor architecture.
