LinkUp Systems L7200 System On Chip Now Supported by Mentor Graphics VRTX Operating System

SANTA CLARA, Calif.----Sept. 25, 2000-- LinkUp Systems Corp. and Mentor Graphics Corporation (Nasdaq:MENT) today announced that the Mentor Graphics® VRTX® Real-Time Operating System (RTOS) supports the LinkUp L7200 System Development Board.

LinkUp Systems L7200 family of processors are multi-functional devices, incorporating an ARM720T(TM) CPU core, an integrated DSP, key peripherals and several serial interfaces on a single System-on-Chip (SoC). The small hardware footprint of the L7200 architecture, combined with the memory-efficient VRTX RTOS, form an ideal solution for SoC-based Internet Appliance applications such as Pocket PCs, Web phones, wireless Internet terminals and smart cellular phones. The addition of VRTX support for the L7200 provides system designers with a high-reliability, pre-ported and configured RTOS, enabling immediate software application development on the L7200 System Development Board (L7200SDB).

``Mentor Graphics, with their VRTX RTOS, is an ideal development partner for LinkUp Systems,'' said Ravi Bhatnagar, president and CEO of LinkUp Systems. ``Together, our companies can offer systems designers a complete OEM solution including an embedded OS, a highly integrated system-on-chip, a complete development environment and reference platforms.''

``VRTX support for the LinkUp Systems L7200 development board provides system designers with the embedded industry's most reliable and highest performance real-time operating system solution for next-generation wireless Internet appliances and communications devices,'' said Michael Kaskowitz, vice president and general manager of the Embedded Software Division of Mentor Graphics. ``The availability of the L7200 development board with the VRTX OS provides OEM customers of both companies with a complete development solution to create reliable, market-ready SoCs for the explosive Internet Appliance market.''
