product brief 21555 Non-Transparent PCI-to-PCI Bridge Revolutionary Bridge Technology for Intelligent I/O and Embedded Applications Product Highlights s developer.intel.com s Non-Transparent PCI-to-PCI bridge technology for high-performance embedded and intelligent I/O applications Independent address spaces and asynchronous clocks deliver unparalleled application flexibility 64-bit primary and secondary bus interfaces deliver high performance for data-intensive applications Compliant with ACPI and PCI bus power management specifications Secondary bus arbitration support for up to nine bus master devices Evaluation Design Kit speeds time-to-market Fully compliant with Revision 2.3 of the PCI specification including delayed transactions Available in 33 and 66 MHz Efficient Management of System and Subsystem Resources The 21555 provides independent primary and secondary address spaces, which allow independent host and local address mapping. With this key feature, local memory requirements need not impact the host address map. The 21555 performs address translation between the primary and secondary buses, resolving address resource conflicts between the host and local address domains. Featuring a subsystem PCI configuration boundary, the 21555 allows the local processor to have complete PCI configuration control of subsystem devices, without host interference. This advanced feature also allows the 21555 to present a subsystem, such as a RAID controller, as a single virtual PC.
