Description: Peripheral Component Interface Technology (Peripheral Component Interconnect PCI) is a new type of high-bandwidth, the processor s bus system has nothing to do. It can serve as a middle layer of the bus can also be used as a peripheral bus system. With other norms would like to control the ordinary bus, PCI bus for high-speed I/O device provides a better support (such as graphics adapters, network interface controllers, disk controllers, etc.). Existing standard to allow 33Mhz using 64 data lines, pure transfer rate up to 2.11Gbps. PCI attractive place but do not lie in its high-speed, it adapted to the modern I/O devices on the system requirements, and require only a few chips can be achieved and to support other bus systems.
