Ethernet 10/100/1000 MAC IP

Ethernet 10/100/1000 MAC (FTGMAC100_S) is an Ethernet controller with DMA functions. This IP includes AHB wrapper for easy integration, DMA engine, on-chip memories (Tx and Rx FIFO), MAC, and MII/ GMII/ RMII interface, which are also part of the functional blocks. FTGMAC100_S provides AHB master capability and is fully compliant with IEEE 802.3 specification for 10/100 Mbps, and IEEE 802.3z for 1,000 Mbps Ethernet specifications. With a DMA engine, this controller can maximize the system performance by reducing the CPU loading while minimizing the FIFO size.

In order to reduce the processing load of the host CPU, FTGMAC100_S implements TCP, UDP, and the IP header checksum generations and validations, and supports the VLAN tagging. For the QoS and CoS requirements, FTGMAC100_S supports high priority queues to reduce the processing load of the host CPU for transmitting packets.
