The Study of the PCI Bus Expansion Based on PCI Bridge Chip

Abstract

PCI (Peripheral Component Interconnect) bus is a high-performance local bus, is put forward to meet the high-speed data transmission between peripherals and host. The CPCI technology is adapted from PCI-based, it conforms to the PCI bus standard and mature European card mechanical standards , supports hot-swap capability, has advantage of the more stronger, more reliable, use and maintenance simply. Can break through the limitations of the PCI card via the PCI bridge technology to achieve PCI to CPCI conversion, the paper introduces the principle of the PCI-PCI bridge technology and in-depth analysis of a typical bridge chip PCI2050, based on a PCI card circuit design example, and provide a reference for the type of system design and verification.
