Increasing Eye Height Margins with PCIe 3.0 Devices
应用文章
The PCI Express® standard first debuted in 2002 as a replacement for the venerable yet tired PCI architecture which had served the PC community well since the early 1990’s. At 2.5 GBit/s, PCI Express 1.0 devices delivered a considerable improvement in performance over the Mbit/s PCI standard. As described by the PCI-SIG®, “PCI Express is a high performance, general purpose I/O interconnect defined for a wide variety of future computing and communication platforms. Key PCI attributes, such as its usage model, load-store architecture, and software interfaces, are maintained, whereas its parallel bus implementation is replaced by a highly scalable, fully serial interface. PCI Express takes advantage of recent advances in point-to-point interconnects, Switch-based technology, and packetized protocol to deliver new levels of performance and features.”
