Accelerated Technology and Tensilica Provide mITRON Support for the Xtensa Configurable Processor with Nucleus uIPLUS

October 31, 2001, Shin-Yokohama, Japan/Santa Clara, Calif. –- Accelerated Technology, Inc. (ATI), the leader of source code and non-royalty based real-time operating system (RTOS) software, and Tensilica Inc., the leading supplier of configurable and extensible processor cores for embedded system-on-chip (SOC) applications, today jointly announced Nucleus uIPLUSsupport for the Xtensa™ processor. ATI and Tensilica will be demonstrating Nucleus uIPLUS at the Tensilica Multimedia Seminar on October 31 at the Shin-Yokohama Prince Hotel in Yokohama, Japan.

The micro-ITRON RTOS specification, developed from the ITRON interface standard has been widely adopted across a large variety of embedded platforms and applications and is now in use by more than 50% of the embedded developers in Japan. As a result there is a large base of software targeted to the mITRON specification. Accelerated Technology’s Nucleus uIPLUS allows customers to take advantage of their mITRON legacy code. ATI and Tensilica have ported Nucleus uIPLUS to Tensilica’s Xtensa processor. The combination of Nucleus uIPLUS and the Xtensa processor will for the first time enable system developers to take advantage of a processor uniquely tailored to the application requirements while preserving software compatibility with the proven and popular mITRON specification. Support for Nucleus uIPLUS is further extended through Nucleus EDE and Nucleus UDB which provide enhanced development and debug environments enabling faster development and more complete optimization for systems built with application-specific Xtensa processors.

“Accelerated Technology has always been at the forefront in developing embedded technology for new and innovative devices. Tensilica’s Xtensa processor architecture represents the latest wave of innovative microprocessor technology. Its configurability has found favor among many of our customers. These factors, coupled with our commitment to the Japanese market, prompted the port of Nucleus uiPLUSto the Xtensa architecture. We are grateful for Tensilica’s support in this effort and we are confident that our mutual customers will benefit greatly from our partnership,” said Neil Henderson, president of Accelerated Technology, Inc.

“Japan is a key market for Tensilica," stated Chris Rowen, CEO and President of Tensilica. "We have had great success engaging with the top electronics companies in both consumer and communications applications. Our partnership with ATI brings the full performance and efficiency of configurable processors to the mITRON world for the first time. The combination of Xtensa and Nucleus uiPLUS addresses our customers' requirements for both leading edge solutions and rapid time-to-market.”
