AIOC Interfaces
Overview
The AIOC interfaces include:
• Gigabit Ethernet MACs
• TDM interface
Note: This interface is only available on the Intel^® EP80579 Integrated Processor
with Intel^® QuickAssist Technology. See Table 47-1, “Base Features of EP80579
SKUs” on page 1730.
• Local Expansion Bus interface
• Controller Area Network interfaces
• IEEE-1588 time synchronization hardware assist unit
• Synchronous Serial Port (SSP)
The details for the TDM interface are available in the software for the Intel^® EP80579
Integrated Processor product line enabling documentation.
Gigabit Ethernet (GbE)
The three Gigabit Ethernet controllers off-load various tasks from the IA-32 core to
improve performance. This off-load is often times referred to as “Network Interface
Card” or NIC functionality.
Provided features fall into these five general categories:
• MAC features
• Host off-loading
• Link interface
• Power Management (Wake On LAN)
• Serial EEPROM Interface
• Integrated DMA
The GbE controller is based on an Intel fourth-generation Gigabit MAC to provide a
standard IEEE 802.3 Ethernet interface for 1000BASE-T, 100BASE-T, and 10BASE-T
applications (802.3, 802.3u, and 802.3ab). The controller is capable of transmitting
and receiving data rates of 1,000 Mbps, 100 Mbps or 10 Mbps.
By using hardware acceleration, the controller is able to off-load tasks, such as
checksum calculations and TCP segmentation from the host processor.
The native interfaces supported by the GbE controller are MII and GMII. Protocol
translation gaskets are used to provide the RMII and RGMII interfaces.
