DESCRIPTION
The Texas Instruments PCI2250 PCI-to-PCI bridge provides a high performance connection path between two peripheral component interconnect (PCI) buses. Transactions occur between masters on one PCI bus and targets on another PCI bus, and The PCI2250 provides two-tier internal arbitration for up to four secondary bus masters and may be implemented with an external secondary PCI bus arbiter. The PCI2250 provides compact-PCI (CPCI) hot-swap extended capability, which makes it an ideal solution for multifunction compact-PCI cards and adapting single function cards to hot-swap compliance. The PCI2250 bridge is compliant with the PCI-to-PCI Bridge Specification. It can be configured for positive decoding or subtractive decoding on the primary interface, and provides several additional decode options that make it an ideal bridge to custom PCI applications. Two extension windows are included, and the PCI2250 provides decoding of serial and parallel port addresses. The PCI2250 is compliant with PCI Power Management Interface Specification Revisions 1.0 and 1.1.
