10/100 Mbps Dual-Speed Ethernet MAC
Overview
The PE-MACMII (TM)provides a 10/100 Mbps Ethernet Media Access Controller (MAC) for incorporation in a customer’s own ASIC design. The PE-MACMII module consists of six sub-modules. These sub-modules comprise the transmit and receive portions of the Ethernet MAC plus three supporting sub-modules. The core is adaptable to a wide range of system requirements. For example, it is designed to interface to 10 or 100 Mbps MII-based PHY devices but the range of PHYs supported can readily be extended by adding one of the optional interface modules that are available for the core. Similarly, the core offers a processor independent 16-bit host interface but can readily be interfaced to a range of standard buses through the addition of bridges such as the optional AMBA AHB Bridge provided with the PE-MACMII core.
