LogiCORE Tri-Mode Ethernet MAC Core - Throughput in half-duplex GMII and RGMII modes

Description

If using the Tri-Mode Ethernet MAC Core in half-duplex mode without the clock enables option when sending back to back frames, you will not be able to get maximum throughput. The minimum IFG will be 17 bytes.

Solution

This only effect half-duplex mode and does not effect full-duplex mode. If needed, full throughput with an IFG of 12 for half-duplex mode can be achieved by using the soft LogiCORE Tri-mode Ethernet MAC with the clock enable option.
