PCI Express System Architecture （体系结构英文版，完整书签）

This specification describes the PCI Express® architecture, interconnect attributes, fabric management, and the programming interface required to design and build systems and peripherals that are compliant with the PCI Express Specification

一方面，在半导体领域，Intel继续一览众小；另一方面，ARM处理器的崭露头角正在开创一个属于更多参与者的帝国。详情请看《ARMx86》。 CI(Peripheral Component Interconnect)总线的诞生与PC(Personal Computer)的蓬勃发展密切相关。在处理器体系结构中，PCI 总线属于局部总线(Local Bus)。局部总线作为系统总线的延伸，主要功能是为了连接外部设备。

PCI Express M.2 specification-Revision 0.7, Version 1.0,November 27, 2012, The M.2M.2 form factor is used for Mobile Add-In cards. The M.2 is a natural transition from the Mini Card and Half-Mini Card to a smaller form factor in both size and volume. The M.2 is a family of form factors that will enable expansion, contraction, and higher integration of functions onto a single form factor module solution. The key target for M.2 is to be significantly smaller in the XYZ and overall volume of the Half-Mini Card used today in mobile platforms in preparation for the very thin computing platforms (for example; Notebook, Tablet/Slate platforms) that require a much smaller solution.
