pcie基本概念及其工作原理介绍：PCI Express®（或称PCIe®），是一项高性能、高带宽，此标准由互连外围设备专业组（PCI-SIG）制 订，用于替代PCI、PCI Extended (PCI-X)等基于总线的通讯体系架构以及图形加速端口（AGP）。 转向PCIe主要是为了实现显著增强系统吞吐量、扩容性和灵活性的目标，同时还要降低制造成本，而这 些都是基于总线的传统互连标准所达不到的。PCI Express标准在设计时着眼于未来，并且能够继续演 进，从而为系统提供更大的吞吐量。第一代PCIe规定的吞吐量是每秒2.5千兆比特（Gbps），第二代规 定的吞吐量是5.0 Gbps，而最近公布PCIe 3.0标准已经支持8.0 Gbps的吞吐量。在PCIe标准继续充分利 用最新技术来提供不断加大的吞吐量的同时，采用分层协议也便于PCI向PCIe的演进，并保持了与现有 PCI应用的驱动程序软件兼容性。 虽然最初的目标是计算机扩展卡以及图形卡，但PCIe目前也广泛适用于涵盖更广的应用门类，包括网络 组建、通信、存储、工业电子设备和消费类电子产品。 本白皮书的目的在于帮助读者进一步了解PCI Express以及成功PCIe成功应用。 PCI Express基本工作原理 拓扑结构 本节介绍了PCIe协议的基本工作原理以及当今系统中实现和支持PCIe协议所需要的各个组成部分。本节 的目标在于提供PCIe的相关工作知识，并未涉及到PCIe协议的具体复杂性。 PCIe的优势就在于降低了复杂度所带来的成本。PCIe属于一种基于数据包的串行连接协议，它的复杂度 估计在PCI并行总线的10倍以上。之所以有这样的复杂度，部分是由于对以千兆级的速度进行并行至串 行的数据转换的需要，部分是由于向基于数据包实现方案的转移。 PCIe保留了PCI的基本载入-存储体系架构，包括支持以前由PCI-X标准加入的分割事务处理特性。此 外，PCIe引入了一系列低阶消息传递基元来管理链路（例如链路级流量控制），以仿真传统并行总线的 边带信号，并用于提供更高水平的健壮性和功能性。此规格定义了许多既支持当今需要又支持未来扩展 的特性，同时还保持了与PCI软件驱动程序的兼容性。PCI Express的先进特性包括：自主功率管理； 先进错误报告；通过端对端循环冗余校验（ECRC）实现的端对端可靠性，支持热插拔；以及服务质量（QoS）流量分级。

一博科技PCB设计指导书VER1.0. 66页常见信号介绍 1.1 数字信号 1.1.1 CPU 常称处理器，系统通过数据总线、地址总线、控制总线实现处理器、控制芯片、存 储器之间的数据交换。 地址总线：ADD* （如：ADDR1） 数据总线：D* （如：SDDATA0） 控制总线：读写信号（如：WE_N），片选信号（如：SDCS0_N），地址行列选择信 号（如：SDRAS_N），时钟信号（如：CLK），时钟使能信号（如：SDCKE）等。 与CPU对应的存储器是SDRAM，以及速率较高的DDR存储器： SDRAM：是目前主推的PC100和PC133规范所广泛使用的内存类型，它的带宽为64位， 支持3.3V电压的LVTTL，目前产品的最高速度可达5ns。它与CPU使用相同的时钟频 率进行数据交换，它的工作频率是与CPU的外频同步的，不存在延迟或等待时间。 SDRAM与时钟完全同步。 DDR：速率比SDRAM高的内存器，可达到800M，它在时钟触发沿的上、下沿都能进行 数据传输，所以即使在133MHz的总线频率下的带宽也能达到2.128GB/s。它的地址 与其它控制界面与SDRAM相同，支持2.5V/1.8V的SSTL2标准. 阻抗控制在50Ω±10 ％. 利用时钟的边缘进行数据传送的，速率是SDRAM的两倍. 其时钟是采用差分方 式。 1.1.2 PCI PCI总线：PCI总线是一种高速的、32/64位的多地址/数据线，用于控制器件、外围 接口、处理器/存储系统之间进行互联。PCI 的信号定义包括两部份(如下图)：必 须的(左半部份)与可选的（右半部份）。其中“# ”代表低电平有效。

PCI Hot-Plug Specification Revision 1.0 The primary objective of this specification is to enable higher availability of file and application servers by standardizing key aspects of the process of removing and installing PCI adapter cards while the system is running. Although these same principles can be applied to desktop and portable systems using PCI buses, the operations described here target server platforms.
