Tokyo and Kariya City, Japan -- Toshiba Corporation and DENSO Corporation, a leading supplier of advanced automotive systems, such as car navigation systems, today announced joint development of world’s first multi OS (operating system) environment (software) for car navigation systems. The multi OS environment provides single-chip support for both µ ITRON, the operating system for embedded devices, and Microsoft® Windows®Automotive and enables to use advanced automotive systems, provided by µ ITRON and multi-media applications such as internet, provided by Microsoft®Windows®Automotive concurrently.

The multi OS environment can be applied to the SoC (system on chip), "NAVIEM" which is used for DENSO’s car navigation systems. "NAVIEM", which is jointly developed by DENSO and Toshiba, features Toshiba’s TX49 embedded CPU.

Demonstration boards of multi-OS-based TX49 processor and DENSO’s car navigation system which incorporates the latest version of "NAVIEM", operating on the multi OS environment, will be featured at the Tron Show 2004 from December 11-13, 2003 at the Tokyo International Forum in Japan.

The TX49 core, based on the RISC architecture developed by MIPS Technologies, Inc., provides full support for SoC, assuring the flexibility required for integration of diverse applications and the scalability required for the integration of wide-ranging functionality. As a result, "NAVIEM" provide automotive designer engineers with the freedom and ability to address diverse requirements with a single-chip solution.

"We expect that this multi OS environment will be at a de facto standard platform for car navigation systems and provide a plenty of benefits to the car users" said Mitsuharu Kato, DENSO managing director in charge of ITS product division.

"We recognize DENSO as a leader in high-performance interface technology for in-car navigation system," said Toshinori Moriyasu, executive vice president of Semiconductor Company at Toshiba Corporation. "Working together, we have developed a solution that supports the key OS for embedded applications in automobiles, and that facilitates rapid development and deployment of cost-efficient navigation systems. We have established a valuable partnership that will advance the introduction of next-generation, high-performance car navigation systems to the marketplace."

"We are excited to add DENSO and Toshiba to our list of partners in one of the most advanced markets for in-vehicle devices in the world," said Bob McKenzie, general manager of Microsoft’s Automotive Business Unit. "We look forward to helping DENSO and Toshiba develop next generation in-vehicle devices that leverage the real-time automotive grade performance and rich PC grade multi-media capabilities inherent in our Windows Automotive platform."

"This design win by Toshiba extends the reach of the industry-standard MIPS architecture into the fast-growing automotive infotainment marketplace," said Jack Browne, vice president of worldwide sales at MIPS Technologies, a leading provider of microprocessor cores and architectures for the embedded industry. "Now consumers will have an enhanced user experience through in-car automotive devices, such as cockpit navigational displays and in-console DVD players, that take advantage of high performance characteristics unique to the MIPS architecture. Moving forward, we will continue to bring innovative technologies to market, such as programmability and multi-threading options to our architecture, to ensure customers can meet and exceed the fast-changing requirements of numerous high-growth embedded markets."
