pci- e-指南规范标准

英文回答：

PCI-Express Standard.

The PCI Express (PCIe) standard defines a high-speed

serial computer expansion bus interface designed to replace

the older PCI, PCI-X, and AGP bus standards. PCIe uses a

point-to-point topology, with each device having its own

dedicated link to the host controller. This allows for much

higher data transfer rates than the shared bus architecture

of the older standards.

PCIe devices are typically connected to the host

controller using a small, rectangular connector. The

connector has a number of pins, which are used to transmit

data, control signals, and power. The number of pins in the

connector determines the number of lanes available for data

transfer. Each lane can transfer data at a rate of up to

2.5 GT/s (gigatransfers per second).

PCIe is a versatile standard that can be used for a

variety of applications, including:

Graphics cards.

Network adapters.

Storage devices.

Sound cards.

USB controllers.

The PCIe standard is constantly evolving, with new

versions being released regularly. The latest version of

the standard, PCIe 6.0, was released in 2023. PCIe 6.0

supports data transfer rates of up to 64 GT/s, which is

four times faster than PCIe 5.0.

PCIe 规范。

PCI Express（PCIe）规范定义了一种高速串行计算机扩展总线

接口，旨在取代较旧的 PCI、PCI-X 和 AGP 总线规范。PCIe 使用

点对点拓扑，每个设备与主机控制器有其自己的专用链接。这允许

比旧标准的共享总线架构更高的数据传输速率。

PCIe 设备通常使用一个小矩形连接器连接到主机控制器。连接

器有多个针脚，用于传输数据、控制信号和电源。连接器中的针脚

数量决定了可用于数据传输的通道数。每个通道可以以高达 2.5

GT/s（每秒千兆传输）的速度传输数据。

PCIe 是一种通用标准，可用于各种应用，包括：

显卡。

网络适配器。

存储设备。

声卡。

USB 控制器。

PCIe 标准不断发展，新版本定期发布。该标准的最新版本

PCIe 6.0 于 2023 年发布。PCIe 6.0 支持高达 64 GT/s 的数据传

输速率，比 PCIe 5.0 快四倍。
