Mentor Graphics and Stonestreet One Announce Integrated Bluetooth Software Stack for Nucleus RTOS Targeting Low Power, Connected Embedded Development

WILSONVILLE, Ore., April 18, 2012—Mentor Graphics Corporation (NASDAQ: MENT) today announced the integration of its flagship Nucleus® Real Time Operating System (RTOS) with the Bluetopia protocol stack from Stonestreet One, a leading provider of Bluetooth software. The third generation of the Nucleus RTOS provides built-in power management capabilities and connectivity features ideally suited for power sensitive, wireless communication applications. The Bluetopia stack is a robust and flexible software tool that, when combined with the Nucleus RTOS, enables developers to create a variety of wireless communication applications with ease and reliability.

The strategic partnership between Stonestreet One and Mentor gives developers an integrated and configured solution for Bluetooth connectivity in the memory-constrained microcontroller environments. The Bluetopia solution is configured specifically for the Nucleus RTOS on the Texas Instruments Stellaris development platform. This technology supports the full set of Bluetooth profiles from Stonestreet One, such as Bluetooth stereo audio playback and serial port profile (SPP). The Bluetopia and Nucleus RTOS, with integrated power management services, is an ideal solution for Bluetooth-enabled, high performance, low power connected devices such as industrial monitors, portable medical and consumer products.

“Our Bluetopia solution is portable across multiple operating systems and processors, and

has shipped in millions of devices,” stated Tim Reilly, founder and president of Stonestreet One. “Integrating Bluetopia with Mentor’s market-leading Nucleus RTOS will enable developers to create innovative products for low power and connectivity with ease and reliability.”

Used in more than 2.3 billion mobile handsets, the Mentor® Embedded Nucleus product is a proven, highly efficient, and reliable operating system. The Nucleus RTOS delivers high performance while optimizing resource usage in a single-OS or multi-OS platform. Built with a framework for high efficiency and power management, the Nucleus RTOS is ideal for memory resource-constrained devices and for systems where maximizing cycles-per-watt to conserve power is critical.

“Stonestreet One, a leading provider of Bluetooth stacks, supports leading silicon partners such as TI and Freescale, which is a key reason why we chose them as a strategic partner,” stated Glenn Perry, general manager of the Mentor Graphics Embedded Software Division. “The seamless integration of Bluetopia with Nucleus will help our customers deliver innovative products that require less power and provide robust connectivity—key for today’s consumer devices.”

The Nucleus ReadyStart platform allows developers to begin developing their value-add applications within minutes of installation by providing an integrated development environment (IDE) that consists of the Nucleus RTOS, optimized drivers/BSP, compiler, and debugger tools. The Nucleus software features separate workflows for BSP, system, and application developers which accelerate porting applications to new hardware. The Nucleus ReadyStart product includes the Mentor Embedded Sourcery™ CodeBench technology, GNU-based integrated development environment (IDE), and the Mentor Embedded Inflexion® UI tool for dynamic 2D/3D user interface creation.
