1.1. Differences between 10GbE MAC IP Core and Low Latency Ethernet 10G MAC IP Core
|Features||Low Latency Ethernet 10G MAC IP Core||10GbE MAC IP core|
|Multispeed operation (10M/100M/1G/10Gbps)||Yes||Yes|
|64-bits Avalon-Streaming (Avalon-ST) interface||Yes||Yes|
|32-bits Avalon-ST interface||Yes||—|
|64-bits XGMII PHY interface||Yes||Yes|
|32-bits XGMII PHY interface||Yes||—|
|GMII and MII PHY interface||Yes||Yes|
|Optional IEEE 1588v2 features||Yes||Yes|
|Optional statistic collections for transmit and receive datapaths||Yes||Yes|
|Optional ECC correction and detection||Yes||—|
|Compliant to IEEE 802.3 – 2008 specification||Yes||Yes|
- 32-bits Avalon-ST interface and 32-bit XGMII PHY interface for reduced pin count.
- ECC correction and detection for all internal RAMs that reside in the MAC. This is to provide status on single bit data correction and multi bit error data detection in the RAM that is impacted by electrical or magnetic interference.
