The OPB EMAC Lite is a reduced version of the OPB 10/100 Ethernet MAC (EMAC). Like the EMAC core, it supports an IEEE 802.3 Media Independent Interface (MII) for interfacing to industry standard Physical Layer (PHY) devices. An IBM On-Chip Peripheral Bus (OPB) is also built-in for interfacing with PowerPC® 405, MicroBlaze™, and other processors. The core supports 10BASE-T and 100BASE-TX/FX compliant PHYs in full or half duplex mode. It is sold as part of the Xilinx® 10/100 Ethernet MAC Solution Package, which also includes the OPB 10/100 EMAC and PLB 10/100 EMAC cores. The Lite core may be used in applications where support for interrupts, back to back data transfers, and statistics counters are not required.
Key Features
- 32-bit OPB master and slave interfaces
- Memory mapped direct I/O interface to registers and FIFOs
- Supports unicast and broadcast Transmit and Receive modes
- Configure with EDK (Embedded Development Kit)
