Raven PCI Bridge ASIC

Arbitration

The PCI master can support parking on the PCI bus. If the PCI master starts a transaction that is going to take more than one beat, the PCI master will continuously assert its request until the transaction has completed. The one exception is when the PCI master receives a disconnect or a retry.

Fast Back-to-Back Transactions

The PCI master does not generate fast back-to-back transactions.

Arbitration Latency

Because the bulk of the transactions on PCI are limited to single-beat transfers, the PCI master does not implement a Master Latency timer.

Exclusive Access

The PCI master is not able to initiate exclusive access transactions.

Address/Data Stepping

The PCI master does not participate in the Address/Data Stepping protocol.

Parity

The PCI master supports address parity generation, data parity generation, and data parity error detection.

Cache Support

The PCI master does not participate in the PCI caching protocol.
