Introduction to PCI Express
PCI Express* Architecture in Communications and Embedded Applications
In communications and embedded applications PCI has been deployed ubiquitously as a local interconnect technology over the last decade. Today's communications and embedded applications are demanding higher bandwidths that push the limits of parallel bus architecture. PCI Express as a high-bandwidth, low pin count, serial, interconnect technology that also maintains software compatibility with existing PCI infrastructure, is uniquely positioned as the logical interconnect technology for products being developed today.
PCI Express in communications and embedded applications offers the following benefits that utilize the trends of convergence and modularity.
Advanced Switching* based on PCI Express Architecture addresses the switch fabric needs of modular communications and embedded hardware platforms as a standard, open fabric technology that includes congestion management, protocol agnostic switching, broadcast/multicast support while reusing the physical and link layers of PCI Express.
The broad adoption of PCI Express in desktop and enterprise market segments enables convergence through the re-use of a common interconnect technology.
As this common interconnect, PCI Express in communications and embedded will benefit from lower costs, a stronger ecosystem and the widespread interoperability associated with the large volumes from the compute and enterprise market segments.
Intel, as the number one silicon provider for both the communications/embedded, computing and enterprise industries, is committed to aligning all of our compute and communications silicon, platforms, solutions and ecosystem enabling with PCI Express.
