The non-transparent bridge feature of PI7C9X110 allows the I/O Processor to be isolated from the Host Processor
and its memory map which avoiding memory address conflict when both host and I/O processors are needed side-
by-side.
PCI based systems and peripherals are ubiquitous in the I/O interconnect technology market today. It will be a
tremendous effort to convert existing PCI based products to be used in PCI Express systems. PI7C9X110 provides
a solution to bridge existing PCI based products to the latest PCI Express technology.
Figure 4-1 Forward and Non-transparent Bridge Mode
In reverse (REVRSB=1) and transparent (TM0=0) mode shown in Figure 3-2, PI7C9X110 becomes a PCI-to-PCI
Express bridge that its PCI bus interface is connected to the host chipset between and the PCI Express x1 link. It
enables the legacy PCI Host Systems to provide PCI Express capability.
PI7C9X110 provides a solution to convert existing PCI based designs to adapt quickly into PCI Express base
platforms. Existing PCI based applications will not have to undergo a complete re-architecture in order to interface
to PCI Express technology.
