Kanagawa and Yokohama, JAPAN – February 20, 2006 – Sophia Systems (CEO: Tasuku Kashihira, JASDAQ: 6942) and Tensilica today announced that Sophia Systems’ JTAG emulators and TOPPERS (Toyohashi Open Platform for Embedded Real-time systems) mITRON (ver 4.0) specification-compliant RTOS (real-time operating system) are available for Tensilica’s new Diamond Standard processors.

“We are very pleased to provide support for Tensilica’s new Diamond Standard processors,” stated Tasuku Kashihira, President, Sophia Systems Co., Ltd. “We have worked with Tensilica’s customers and support Tensilica’s Xtensa configurable processors.”

“Our Xtensa customers have enjoyed working with Sophia Systems for debugging and operating system support,” stated Steve Roddy, Tensilica’s vice president of marketing. “We are happy that these products from Sophia Systems will now be available to our Diamond Standard processor customers.”

"We are very pleased to hear that Sophia Systems and Tensilica will provide mITRON-compliant RTOS developed by TOPPERS for Tensilica's Diamond Standard processors," stated Hiroaki Takada, Chairman of TOPPERS Project and Professor of Nagoya University. "We will continue our effort to develop and provide useful open-source software for promoting the development of embedded systems."

Sophia Systems’ compact, USB-powered EJ-Debug™ JTAG emulator is a development tool for ASICs containing Diamond Standard processors and the on-chip debug interface for debugging. EJ-Debug works with Sophia Systems’ easy-to-use Watchpoint software.

TOPPERS is a project aimed at developing various open-source software for embedded systems, including RTOS compliant to mITRON specification. The project is undertaken by a non-profit organization that is led by Professor Hiroaki Takada of Nagoya University and enrolls about 100 organizations of industry, academia, and public sector and about 90 individual engineers. A key objective of the TOPPERS project is to develop many embedded software programs based on the ITRON specification. ITRON is very popular for use in a wide range of embedded systems from Internet access devices to games.
