PCI总线技术的发展

PCI Development of bus technology

PCI总线属于计算机总线的一种,其具有强大的兼容性能,功能也比较全面、系统,能够兼容并支持多组外围设备,不容易受到处理器的限制,实现了数据通路的高性能,提高了它的吞吐量,降低了其延迟性能,为CPU及高速外围设备提供了良好的数据通路。自PCI总线在90年代初推出以来,历经PCI、PCI X、PCI EXPRESS总线技术,总线性能得到了突飞猛进的提高,本文从总线技术的发展,分别介绍各种PCI总线技术的特点的应用。

PCI bus is a kind of compatibility of the strongest and most versatile of the computer bus, he can simultaneously support multiple groups of peripheral devices, and are not subject to the processor with high performance, high throughput, low latency data path for CPU and high-speed peripheral equipment？ Since the launch of the PCI bus in early 90 s, after PCI, PCI X, PCI EXPRESS bus technology, bus performance has been improved by leaps and bounds, this article from the development of bus technology, introduces the various application characteristics of PCI bus technology？
