  Safety-Critical Systems

Business Wire

WILSONVILLE, Ore. -- October 17, 2013

Mentor Graphics Corporation (NASDAQ:MENT) today announced a new version of the
Nucleus® real time operating system (RTOS) targeting high-performance,
next-generation applications for connected embedded devices. The Nucleus RTOS
introduces a lightweight and scalable process model that provides partitioned
and protected memory regions for increased system reliability in
safety-critical applications, including medical, industrial and aerospace. In
addition, the Nucleus software trace technology has also been enhanced to
include support for middleware stacks, enabling performance and power

“This new version of the Nucleus RTOS allows embedded developers to deliver
advanced, sophisticated products with features that you would expect from more
general purpose operating systems,” said Rajeev Kumar, director of worldwide
marketing and business development for Freescale’s Microcontroller business.
“Nucleus provides outstanding value by providing advanced system reliability
in an affordable package — ideal for high-end devices using the Freescale i.MX
family of processors.”

System Reliability and Partitioning

The Nucleus software trace technology, built on the Mentor® Embedded Sourcery™
Analyzer tool, provides even greater system visibility with trace support for
middleware stacks. The software also provides a common time reference to
analyze variables and events across the entire system, the Nucleus RTOS
kernel, application project, and middleware stack in order to optimize the
full system for performance as well as resource utilization and power

With the new Nucleus RTOS process model, embedded system developers can
partition their device modularly and isolate software sub-systems in order to
protect against faults that can bring down the entire system. Memory
partitioning is also useful for field upgrades and optimizing resource
utilization by loading only the files needed based on runtime requirements —
as requirements change modules can be uninstalled and additional modules

“Our latest Nucleus release was developed to serve today’s advanced and highly
connected embedded devices with high-performance and cost-efficient
networking, security and graphics requirements,” said Scot Morrison, general
manager of Runtime Solutions, Mentor Graphics Embedded Software Division.
“Nucleus delivers unmatched value by delivering robust system reliability with
space partitioning and device optimization with cutting-edge system data
visualization capabilities.”

Middleware Data Visualization for Optimum Device Performance

Based on the award-winning Sourcery Analyzer technology, Nucleus software
trace provides unparalleled data visualization capability in a system using a
common time reference that correlates all aspects of the connected device. The
Nucleus software trace tool associates Nucleus RTOS tasks, network IP
activity, device activity, and power management metrics to allow system debug
and device tuning for optimal performance using a single data visualization

The Nucleus RTOS with Nucleus process model currently supports device families
based on ARM MMU-enabled cores from semiconductor suppliers including Altera,
Freescale, Texas Instruments and Xilinx.
