The paper holds the idea that, parallel bus can;t adapt to high-speed transfers due to self-limitations, and high-speed serial point-to-point bus will substitute for traditional parallel bus; data transfer will not be carried out simply by drive circuit and parallel bus, but by special high-speed serial bus; the traditional mode of single bus loading multi-device is disappearing, and a centralized switch module is replacing the bus function in a mode of one switch module connecting all devices via high-speed point to point serial bus.

文章认为并行总线由于自身缺陷，已经不适合进行高速传输，高速串行点对点连接将代替传统的并行接口；数据交换也不再是简单地通过驱动电路和并行数据线进行，而是通过特殊的串行高速总线连接；传统的在一条总线上同时挂载多个设备的模式正逐渐消亡，总线功能已被一个集中式的交换模块取代，而交换模块和各个设备都是通过高速串行点对点的方式进行连接。
