| 词条 | Root complex |
| 释义 |
In a PCI Express (PCIe) system, a root complex device connects the processor and memory subsystem to the PCI Express switch fabric composed of one or more switch devices. Similar to a host bridge in a PCI system, the root complex generates transaction requests on behalf of the processor, which is interconnected through a local bus. Root complex functionality may be implemented as a discrete device, or may be integrated with the processor. A root complex may contain more than one PCI Express port and multiple switch devices can be connected to ports on the root complex or cascaded.[2] References1. ^{{cite web | url = https://pcisig.com/sites/default/files/files/PCI_Express_Basics_Background.pdf#page=26 | title = PCI Express Basics and Background | date = 2015-06-17 | accessdate = 2016-04-12 | author = Richard Solomon | publisher = PCI-SIG | format = PDF | page = 26}} {{Compu-hardware-stub}}2. ^{{cite web |url=http://www.rtcmagazine.com/articles/view/100327 |title=Choosing the Right Programmable Logic Solution for PCI Express Applications |accessdate=31 March 2010 |deadurl=yes |archiveurl=https://web.archive.org/web/20110221044635/http://www.rtcmagazine.com/articles/view/100327 |archivedate=21 February 2011 |df= }} 1 : Peripheral Component Interconnect |
