CriticalBlue and MontaVista Partner to Expand Multicore Software Development Solutions for Embedded
Linux

Support for Prism on MontaVista Linux will drive faster adoption of multicore platforms and
deployment of end products on leading commercial Linux platform

SANTA CLARA, Calif. - December 21, 2009 - MontaVista(r) Software LLC, a leader in embedded Linux(r)
commercialization, and CriticalBlue, a pioneer in embedded multicore software analysis, exploration
and verification tools, announced today CriticalBlue has joined the MontaVista partner program and
will make their Prism product available on MontaVista Linux 6 and Montavista Linux Carrier Grade
Edition products.

This announcement continues the broadening of Prism integrations with key players in the multicore
software development eco-system by adding support for an industrial strength, commercial quality
Linux. Prism is an award winning embedded multicore programming system which allows software
engineers to easily asses and realize the full potential of multicore processors without
significant change to their development flow. Prism analyzes the behavior of code running on either
hardware development boards or simulators. It allows engineers to take their existing sequential
code, and without making any changes, explore and analyze opportunities for concurrency. Having
identified the optimal parallelization strategy in this way, the developer will implement parallel
structures, and use Prism again to verify efficient and thread-safe operations.

MontaVista Linux is the first commercial Linux provider to be supported by Prism. The Prism Eclipse
plug-in will be integrated into the MontaVista DevRocket integrated development environment (IDE),
providing the most advanced embedded Linux development environment for multicore software on the
market. MontaVista customers will now be able to quickly analyze the potential benefit of new, high
performance, multicore software platforms for their existing application code and develop new code
and quickly tune it for operation on multicore processors, all within a single MontaVista DevRocket
environment, and all in the familiar Eclipse framework.

Prism is available today for ARM and MIPS cores with several other leading multicore processor
architectures coming in Q1 2010.

Supporting Quotes:
"Developers need to analyze their real world applications running on commercial Linux platforms
like MontaVista Linux using common frameworks like Eclipse," said David Stewart, CEO, CriticalBlue.
"By partnering with MontaVista, and integrating with the MontaVista DevRocket IDE, Prism will
support the broadest range of platforms on a commercial quality Linux, allowing our joint customers
a way to rapidly ensure safe and timely migration of their software onto multicore platforms and
efficient exploitation of the parallelism inherent within."

"By combining CriticalBlue's Prism solution, MontaVista Linux and MontaVista DevRocket, our
customers will benefit from the most advanced multicore integrated development environment
available for embedded Linux," said Dan Cauchy, vice president, marketing at MontaVista Software.
"This integrated environment will allow developers to quickly analyze, convert and tune sequential
code into parallel code and harness the full capabilities of MontaVista Linux running on modern
multicore processors."
