Loongson-1B Gigabit Ethernet MAC Controller is based on
|
|
Synopsys DesignWare MAC (version 3.50a).
|
|
|
|
Main features
|
|
- Dual 10/100/1000Mbps GMAC controllers
|
|
- Full-duplex operation (IEEE 802.3x flow control automatic transmission)
|
|
- Half-duplex operation (CSMA/CD Protocol and back-pressure support)
|
|
- RX Checksum Offload
|
|
- TX Checksum insertion
|
|
- MII interface
|
|
- RGMII interface
