SAN FRANCISCO--(BUSINESS WIRE)--April 24, 2003

Accelerated Technology(R), the Embedded Systems Division of Mentor Graphics Corporation (Nasdaq:MENT), today announced the availability of the Nucleus(TM) NET embedded TCP/IP protocol stack for networking developers using the micro-ITRON specification.

This release of Nucleus NET allows micro-ITRON users to develop their networking application with a source code, royalty-free software solution.

The micro-ITRON Real-Time Operating System (RTOS) specification, developed from the ITRON interface standard, has been widely adopted across a large variety of embedded platforms and applications. It is now in use by more than 50 percent of the embedded developers in Japan. As a result, there is a large base of application software targeted to the micro-ITRON specification such as consumer electronics, retail automation and telecommunications.

In the past, there has been an absence of quality middleware products for micro-ITRON developers to use. The micro-ITRON compatible Nucleus NET now addresses the networking middleware requirements and offers developers a royalty-free solution for building networking applications using micro-ITRON standards. Designed for the unique requirements of the embedded environment, Nucleus NET is a scalable, high performance embedded TCP/IP protocol stack. Support for the following protocols is included within Nucleus NET: TCP, UDP, IP, BOOTP Client, IGMP, ICMP, ARP, RARP, DNS Resolver, DHCP Client, RIP version I/II, TFTP Client.

"Accelerated Technology was among the early adopters of the micro-ITRON specification, releasing a version of our Nucleus kernel compatible with the specification in January of 2000," said Robert Day, director of marketing for the Embedded Systems Division of Mentor Graphics. "We continue to broaden our link with the micro-ITRON standard by offering these new compatible networking products and also becoming the North American Liaison Office of the TRON Association." (See press release entitled "Accelerated Technology; Official North American Liaison Office of the TRON Association" 4/23/03.)
