Bridge Benefits and Features

• PCI and PCI-X Bridges allow a system to add more devices
  • Creates a separate secondary bus
  • Permits more devices or "loads" to be added to the system
    • Allows for more slots for adapter cards in a system
    • Allows for multiple devices on a line card or add-in card

PCI Express Reversible Bridges

The PI7C9X110 is composed of one x1 PCI Express port and one standard 32-bit / 66MHz PCI port.

The versatile PI7C9X110 is capable of both “forward” and “reverse” bridging. In “forward” mode, the PI7C9X110 is configured with the PCI Express port on the primary and the PCI port on the downstream side.

The typical usage in this configuration is to “bridge” legacy PCI product to PCI Express systems.

In “reverse” mode, the PI7C9X110 is configured with the PCI port on the primary and the PCI Express port on the downstream side.

The “reverse” configuration will be mainly used to “bridge” new PCI Express products to legacy PCI systems.
