ICM Features
ICM Functional Description
1
The ICM is provided for backward compatibility only. New designs using the
Avalon-ST interface should use the Avalon-ST PCI Express MegaCore instead.
Figure B–23. Design Example with ICM
The ICM provides the following features:

■
A fully registered boundary to the application to support design partitioning for
incremental compilation
An Avalon-ST protocol interface for the application at the RX, TX, and interrupt
(MSI) interfaces for designs using the Avalon-ST interface
Optional filters and ACK’s for PCI Express message packets received from the
transaction layer
Maintains packet ordering between the TX and MSI Avalon-ST interfaces
TX bypassing of non-posted PCI Express packets for deadlock prevention
