一种高性能I／O互连协议链路接口的实现

随着计算机技术的发展，传统的PCI总线已难以满足应用的要求，Hyper Transport采用低电压差分信号传输、点到点互连，可提供更高的数据传输率和可扩展性，满足各种不同的需求。本文对Hyper Transport链路接口的链路初始化、错误处理和高速链路源同步关键技术进行了研究，提出了相应的实现方法。

Implementation of the Link Interface of a High-Performance I/O Interconnect Protocol

With the development of computer technologies, the traditional PCI bus can hardly meet the emerging requirements. HyperTransport uses low voltage differential signals to transmit information and realize point-to-point interconnect. It can afford higher data transfer rates and scalabilities to meet various application requirements. In the paper, we study the following key techniques in the HyperTransport link interface : link initialization, error handling and high-speed link source synchronization, and give the corresponding implementation methods.
