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。

Compact PCI（Compact Peripheral Component Interconnect）简称CPCI，中文又称紧凑型PCI，是国际工业计算机制造者联合会（PCI Industrial Computer Manufacturer's Group，简称PICMG）于1994提出来的一种总线接口标准。是以PCI电气规范为标准的高性能工业用总线。为了将PCI SIG的PCI总线规范用在工业控制计算机系统，1995年11月PCI工业计算机制造者联合会（PICMG）颁布了CPCI规范1.0版，以后相继推出了PCI-PCI Bridge规范、Computer Telephony TDM规范和User-defined I/O pin assignment规范。
