21. 4 Introduction 5AX 1 4 BLOCK DIAGRAM PBSRAM Introduction 1 5 INTRODUCE THE PCI BUS Connecting devices to CPU local bus can dramatically increase the speed of I O bound peripherals with only a slight increase in cost over traditional systems This price Performance point has created a vast market potential for local bus products The main barrier to this market has been the lack of an accepted standard for local bus peripherals Many mainboard and chipset manufactures developed their own local bus implementations but they are incompatible with each other The VL Video Electronics Standards Association local bus and PCI Peripheral Component Interconnect bus specification was created to end this confusion The PCI bus standard under development since Jun 1992 which is designed to bring workstation level performance to standard PC platform The PCI bus removes many of the bottlenecks that have hampered for several years On the PCI bus peripherals operate at the native speed of the computer system thus enabling data transfer between peripherals and the system at maximum speed This performance is critical for bandwidth constrained devices such as video multimedia mass storage and networking adapters PCI bus standard provides end users with a low cost extendible and portable local bus design which will allow system and peripherals from different manufactures to work together
