General Description

ꢀ Hardware assisted Buffer and Queue

Management

The EA-208 provides the Ethernet network access interface. It supports 6 ports of 10Mbps

Ethernet and 2 ports of 10/100 Mbps Ethernet. The 10Mbps ports uses serial interface to con-

nect with external 10BaseT or other 10Mbps PHY devices. For 10/100 Mbps ports, MII inter-

face is used to connect external PHY devices.

Registers & Local Buffer Memory

Big and Little Endian CPUs

The EA-208 provides the MAC protocols, handles the local buffer memory interface and man-

agement, arbitrates among multiple priority queues, and interfaces with the XpressFlow Engine

and other Access Controllers through the XpressFlow message passing protocol.

Direct interface to standard micro-

processors, including 386, 486

families and Motorola MPC series

embedded processors
