PCI Arbitration Assignments on Host Boards

The IPMC module PCI arbitration is provided by the host board.

MVME5100

The MVME5100 PCI arbitration is performed by the Hawk ASIC on the host board which
supports eight external PCI masters. Included is the Hawk itself and seven external PCI
masters. The arbitration assignments for the IPMC712 and IPMC761, when installed on the
MVME5100, are as follows:

Request 2 (PARBI2)

MVME5500

The MVME5500 IPMC module PCI arbitration is performed using logic implemented in
Programmable Logic Devices (PLDs). These arbiters use a rotating priority scheme for fairness
and bus parking and will always be on the GT-64260B. There are no software programmable
modes to these arbiters.
