Nucleus RTOS and Development Tools Now Available for Networking Developers Using Freescale Semiconductor's ColdFire Processors

MOBILE, Ala., July 28, 2004 - Accelerated Technology®, the Embedded Systems Division of Mentor Graphics Corporation (Nasdaq: MENT), today announced that its Nucleus® Real-Time Operating System (RTOS) and comprehensive development environment supports Freescale Semiconductor, Inc.'s ColdFire® MCF547x/548x processors. Embedded developers using these processors now have a complete software solution available from one vendor in which to build, compile and debug their network-connected control applications.

The MCF547x and MCF548x families of microprocessors, based on the advanced V4e ColdFire core, offer the highest level of integration and include features such as memory management unit (MMU), floating point unit (FPU), enhanced multiplier-accumulator unit (EMAC) and on-chip multiprocessing. The Nucleus RTOS, closely integrated with the MCF547x/548x processors, provides a customized and solid foundation from which ColdFire processor developers can build applications such as point-of-sale systems, robotics, security systems and healthcare-related medical instrumentation.

By implementing the robust and scalable Nucleus RTOS, developers can take advantage of other Nucleus add-on products supporting the MCF547x/548x processors including the Nucleus NET TCP/IP networking protocol stack, the Nucleus SHELL debug tool, Ethernet drivers and a controller area network (CAN) driver (CAN is specific to the MCF548x only).

Accelerated Technology's development tool suite is also available for the MCF547x/548x processors. The XRAY® debugger provides powerful debugging capabilities with a consistent feature-set and user interface for all popular development hosts. The Microtec® compilation tools consist of C and C++ cross-compilers, assembler and linker that help developers take advantage of the new Freescale chip variants as they are released. Rounding out the tool suite for ColdFire processor developers is the code|lab® EDE software, which provides an intuitive, integrated embedded development environment.

"Accelerated Technology has a long history of helping Freescale's 32-bit embedded customers with industry-proven products such as the Nucleus RTOS and the XRAY Debugger," said Bill Krakar, tools program manager, Freescale Semiconductor. "The combination of Accelerated Technology's long-time embedded expertise with Mentor Graphics' global capabilities will help Freescale's new and existing customers achieve success with their MCF547x/548x designs."

"The Nucleus software has always been popular in network-connected control applications due to its technical merit as well as its royalty free business model. The Nucleus RTOS offers the functionality necessary for these applications, and the small code footprint fits nicely within the limited system resources," said Robert Day, director of marketing, Embedded Systems Division, Mentor Graphics. "Supporting the new Freescale ColdFire 548x/7x processors with our RTOS and development tools offers a very appealing solution for developers embarking on new networking designs."
