Overview

The EP440 is a 32-bit PCI-to-PCI transparent bridge used for bus expansion. With the bridge IP core, the PCI bus system can be expanded virtually without limit to accommodate many PCI devices. Based on address mapping programmed to the core, the bridge selectively forwards transactions across the primary and secondary buses while keeping local transactions local to minimize bandwidth consumption. The bridge is capable of configuring all the secondary bus devices. The bridge has dual write buffer in each direction to handle simultaneous transactions on both the primary and secondary bus. Read transactions across the bridge are handled as delay read according to the PCI bridge specification. All different types of transfer termination and exceptions are handled by the core and all transaction ordering rules are observed strictly by the PCI bridge core. It is a transparent bridge so software alternation is not required. Multiple PCI bus segments can be built with several PCI bridges.
