What is PCI Express?
With the spread of broadband and digital media in recent years, the need has arisen in each application to process large amounts of data in a short time. The PCI bus that has been used in PCs, servers, communication equipment and various embedded devices has become a bottleneck for system performance due to the increasing amounts of data being handled in high-end storage devices and gigabit network communications. PCI ExpressTM, a more efficient data processing standard set to replace the PCI bus, was established for this reason.
PCI Express is a next-generation PCI bus interface standard advocated by Intel Corporation and approved and released by the PCI Special Interest Group (SIG). PCI Express consists of a serial bus that is downwardly compatible with the PCI bus, supports rates of up to 2.5 Gbps or 5.0 Gbps per lane and up to 32 lanes, and realizes an extremely wide data band.
With the rapidly increasing demand for greater data bandwidth between chips, the traditional parallel PCI bus specification is nearing the limit of its capabilities. PCI Express was devised to provide a solution to such a situation.
