1.3.1

PCIe Interface

The PCIe Interface performs all the physical, data link, and transport layer protocols associated with PCIe.

1.3.2

S-RIO Interface

The S-RIO Interface performs all the physical and transport layer protocols associated with S-RIO.

1.3.3

Messaging Engine

The Messaging Engine uses S-RIO messaging logical layer functions with dedicated messaging DMA channels per Tx queue

and per Rx queue.

1.3.4

Mapping Engine

The Mapping Engine maps between PCIe and S-RIO transactions, including segmentation and reassembly as required.

1.3.5

Block DMA Engine
