GDA Delivers UNH-IOL 10 Gigabit Ethernet MAC IP Core for ASIC, FPGA

8/29/2003 - GDA Technologies, Inc., a fast growing supplier of Intellectual Property (IP) and Electronic Design Services (EDS), announced XGEMAC[Prakash1], the industry’s first UNH-IOL Compliance Validated 10 Gigabit Ethernet Media Access Controller, citing it as an important building block in the infrastructure needed to advance 10Gigabit Ethernet 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. The XGEMAC has successfully completed interoperability testing conducted 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,” said 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. We are very happy to see GDA leading this new trend in IP business in which the vendors are going all the way in creating system implementations and compliance validation. It aligns very well with our charter at UNH IOL of fostering industry wide 10G Ethernet interoperability and compliance.”

“The XGEMAC is a cost-effective, highly configurable and end-to-end system validated solution for switch, router and NIC designers,” said 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.

“10 Gigabit Ethernet is the continuation of the Ethernet evolution within and beyond the enterprise and will enable end-to-end Ethernet network topologies. 10Gigabit Ethernet will speed the proliferation of Ethernet technology into MAN, WAN, Storage Area Networks (SAN) and Network-Attached Storage (NAS) markets due to its economics, simplicity and interoperability, “said AGK, President of GDA Technologies. “The XGEMAC is a great contributor to the proliferation of Ethernet technology into the mass networking market.”
