Tensilica and MontaVista Software Partner to Create First Embedded Linux Operating System for a Configurable Processor

Companies Establish Technical and Marketing Alliance

Santa Clara and Sunnyvale, Calif., September 4, 2001 — In a joint announcement, MontaVista Software Inc., the company powering the embedded revolution and Tensilica, the leading supplier of configurable processor cores for embedded systems, today disclosed a wide-reaching technical and marketing agreement. The pact leads to the porting of MontaVista Software’s Hard Hat Linux, one of the most widely used embedded Linux products to Tensilica’s Xtensa processor architecture.

The combination of Hard Hat Linux with the Xtensa architecture will enable development of a broad range of communications and consumer products previously built with proprietary controllers or rigid processors, to exploit the incredible flexibility of Tensilica’s configurable processor core. For the first time SOC developers will be able to harness the enormous array of Linux application software on an application-optimized processor. Utilizing Tensilica’s OSKit™ technology, Hard Hat Linux will be automatically updated to fully support all possible configurations that meet or exceed the minimum requirements. This will enable Hard Hat Linux to run “out of the box” on the customized configurations.

This is a good move for both companies,” said Jerry Krasner, Ph.D., Executive Director of CMP’s Electronics Markets Forecasters. “It’s a big win for MontaVista Software in that it will augment and accelerate the diffusion of Hard Hat Linux in the embedded space. And for Tensilica, adding a Linux port to the other supported RTOSs will make Xtensa an even more attractive option to embedded systems designers.”

"We are committed to providing best-of-breed software foundations to our customers,” said Tensilica’s president and CEO, Chris Rowen. “MontaVista's Hard Hat Linux is the perfect marriage of the true industrial-strength Linux operating system with optimized embedded support. Few other embedded processor architectures, fixed or configurable, can match our new advanced memory management capabilities for robust software environments like Linux. We welcome MontaVista to our Xtensions™ Network, and anticipate close collaboration in the proliferation of Linux across the full spectrum of communications and consumer applications.”

"As the company powering the embedded revolution, we target the most advanced products such as Tensilica's configurable architecture,” said Jim Ready, CEO and President, MontaVista Software. "Together, Xtensa technology and Hard Hat Linux bring a scalable, robust and flexible platform to embedded developers, allowing them to reduce their time to market and total costs. "

The Xtensa processor is targeted at high volume applications including datacom and telecom protocol processing, digital cameras, set top boxes, office automation products, wireless communications devices, and a spectrum of other consumer electronic products. Announced licensees of the Xtensa processor include Broadcom, Cisco Systems, Conexant Systems, Fujitsu Limited, Hughes Network Systems, JNI Corporation , Marvell (Galileo Technology), Mindspeed Technologies, National Semiconductor, NEC Corporation, NTT, ONEX Communications TranSwitch and Zilog.
