This paper first analyzed the key issues caused by PCIE signal interconnection in CPCI platform such as the signal integrity , power integrity and electromagnetic compatibility .

首先分析了CPCI平台下PCIE信号互连引起的信号完整性、电源完整性、电磁兼容等关键问题。

The traditional parallel bus bandwidth can no longer meet the needs of the current system , and is replaced by the third generation of high-speed serial bus which takes PCIE as the core .

传统的并行总线带宽已不能满足当前系统的需求，取而代之的是以PCIE为核心的第三代高速串行总线。

With SR-IOV , a PCIe device can export not just a number of PCI physical functions but also a set of virtual functions that share resources on the I / O device .

通过SR-IOV，一个PCIe设备不仅可以导出多个PCI物理功能，还可以导出共享该I/O设备上的资源的一组虚拟功能。

SR-IOV accomplishes this by extending virtual functions to the various users , which appear as physical functions of the PCIe space but are represented within the card as shared functions .

SR-IOV通过将虚拟功能扩展到各种用户来实现，这是作为PCIe空间的物理功能，但是在卡中作为共享功能表示。

Another variation , called Multi-Root IOV , supports larger topologies ( such as blade servers , where multiple servers can access one or more PCIe devices ) .

另一个变体（称为Multi-RootIOV）支持大型拓扑（比如刀片服务器，其中多个服务器能够访问一个或多个PCIe设备）。

Some restrictions apply in PCI ( for example , PCI devices behind a PCIe-to-PCI bridge must be assigned to the same domain ), but PCIe does not have this restriction .

PCI中有一些限制（例如，一个PCIe-to-PCI桥接器后面的PCI设备必须被分配到相同的域），但PCIe没有这种限制。

As the latest bus and interface standard , PCIE ( PCI-Express ) has gradually become the mainstream as it can reach10GB / s and also there is considerable potential for the development .

PCIE（PCI-Express）作为目前最新的总线和接口标准，最高能够达到10GB/s，而且还有相当大的发展潜力，已经逐渐成为总线和接口标准的主流。

The PCIE bus is the next-generation bus standard , characterized by high transmission speed and large amount of throughput and single-link effective data rate of 2Gb / s , as well as multiple links simultaneously transmit .

而PCIE总线，作为新一代的总线标准，具有传输数据量速度快，吞吐量大，单条链路有效数据速率为2Gb/s，同时还具有多条链路同时传输的优点。

The paper first introduces the topology structure of PCI Express bus , the level of device connected to the PCIe bus , rules of transactions which include read and write requests , and configuration space for PCIe device .
