GDA Technologies intros UNH-IOL-compliant 10-GbE MAC IP core

2 September 2003 San Jose, CA Lightwave -- GDA Technologies Inc., supplier of Intellectual Property (IP) and Electronic Design Services (EDS), has introduced what it claims is the industry's first UNH-IOL Compliance Validated 10-Gigabit Ethernet (10-GbE) Media Access Controller, an important building block in the infrastructure needed to advance 10-GbE transport technology into wide area, metro, and local area networks.

The XGEMAC is a rich featured, highly configurable core and is fully compliant to the IEEE 802.3ae specification, say company representatives. The XGEMAC successfully completed interoperability testing at the University of New Hampshire (UNH-IOL) InterOperability Laboratory on July 25, 2003.

"GDA's highly flexible system validation platform, exhaustively validated XGEMAC design, and their in-house Ethernet expertise allowed them to complete the conformance testing very quickly, in just a few days," reports Bob Noseworthy, 10-Gigabit Ethernet Consortium manager at the University of New Hampshire InterOperability Lab. "GDA's XGEMAC IP successfully completed all the 10-Gigabit Ethernet conformance tests and hence offers additional confidence to its future licensees that their products will be in compliance with IEEE 802.3ae specification."

"The XGEMAC is a cost-effective, highly configurable and end-to-end system validated solution for switch, router, and NIC designers," adds Prakash Bare, Vice President of IP Business at GDA Technologies Inc. "Through the XGEMAC offering, we provide the system designers a 10-Gigabit Ethernet MAC design that has low latency, high throughput, small foot print, and is ready-to-go for easy integration into ASIC and FPGA implementations."

The XGEMAC adheres to the IEEE 802.3ae standard and is available for both ASIC and FPGA implementations. Its simple, configurable, and modular architecture is independent of application logic, PHY designs, implementation tools, and--most importantly--target technologies. The XGEMAC provides XGMII interface to the line side and a flexible backend interface to the user logic on the system side. The XGEMAC has an extensive set of filtering capabilities based on source, destination, unicast, multicast, and broadcast addresses as well as being VLAN aware. The optional FIFO module supports configurable depths and watermarks with a variety of control options to support lossless flow control. The core also provides rate matching for OC-192 PHY components and a full set of statistics counters to support SNMP/RMON.

The XGEMAC and the IP validation platform are available now.
