system block diagram – 16-bit PC Card interface

A simplified system block diagram using the PCI1031 is provided below. The PCI950 IRQ deseralizer and the

PCI930 zoomed video (ZV) switch are optional functions that can be used when the system requires that

capability.

The PCI interface includes all address/data and control signals for PCI protocol. The 68-pin PC Card interface

includes all address/data and control signals for 16-bit (R2) protocols. When zoomed video (ZV) is enabled (in

16-bit PC Card mode) 23 of the 68 signals are redefined to support the ZV protocol.

The interrupt interface includes terminals for parallel PCI, parallel ISA, and serialized PCI and ISA signaling.

Other miscellaneous system interface terminals are available on the PCI1031 that include:

D Multifunction IRQ terminals

D SUSPEND, RI_OUT (power management control signals)

D SPKROUT.

video signals too the VGA controller.
