PCI(外设部件互连)是当今个人计算机的主流总线结构，是微型计算机中处理器/存储器与外围控制部件、扩展卡之间的互连接口。PCI局部总线规范是互连机构的协议，也是电气和机械配置的规范。 本书分为9章，涵盖了PCI局部总线规范2.2版及其最新进展，详细介绍了PCI局部总线的原理和操作，内容包括PCI局部总线的基本概念、信号的定义、总线的操作、电气规范、机械规范、配置空间、66 MHz规范、BIOS和PCI-PCI桥等。书中通过大量的时序波形和实例对PCI局部总线的实际应用进行了深入浅出的阐述。 -PCI (peripheral device part interconnection) is now personal computer s mainstream bus structure, is in the microcomputer the processor/memory and between the periphery control portion, the expansion card interconnection connection. The PCI local bus standard is the interconnection organization agreement, is also the standard which the electricity and the machinery dispose. This book divides into 9 chapters, has covered the PCI local bus standard 2.2 edition and the newest progress, introduced the PCI local bus s principle and the operation in detail, the content including the PCI local bus s basic concept, the signal definition, main line s operation, the electricity standard, the mechanical standard, the disposition space, 66 MHz stand
