EMAC8_W - Wishbone 8-bit Standard Ethernet Media Access Controller
Figure 1. EMAC8_W - Wishbone 8-bit Standard Ethernet Media Access Controller.
The 8-bit Standard Ethernet Media Access Controller component (EMAC8_W) is a Wishbone-compliant component providing an interface between a processor and a standard Physical Layer device (PHY) through support of the IEEE802.3 Media Independent Interface (MII).
Supply of this soft core under the terms and conditions of the Altium End-User License Agreement does not convey nor imply any patent rights to the supplied technologies. Users are cautioned that a license may be required for any use covered by such patent rights.
Features at-a-glance
- 10/100Mbps at Full/Half Duplex
- Independent single message buffering – both send and receive
- MII compatible interface for connecting external 10/100Mbps PHY transceivers
- Ethernet/IEEE802.3 compatible
- No lower limit for external (system) clock frequency
- Wishbone-compliant
Availability
From an OpenBus System document, the EMAC(8) 10-100 component can be found in the Peripherals region of the OpenBus Palette panel.
From a schematic document, the EMAC8_W component can be found in the FPGA Peripherals (Wishbone) integrated library (FPGA Peripherals (Wishbone).IntLib), located in the \Library\Fpga folder of the installation.
