64-BIT Risc Processor Set To Enter Space Service
MIPS Technologies, Inc. said Monday that the first 64-bit RISC microprocessor chip for space applications has been developed by High-Reliability Components Corporation (HIREC) of Tokyo, under contract to the National Space Development Agency of Japan. The microprocessor chip is based on MIPS Technologies' leading 64-bit processor architecture for high-performance, low-power embedded applications. Development of the microprocessor chip was a collaborative effort, led by HIREC, among leading technology providers. Toshiba Corporation, a licensee of the MIPS architecture, developed the 64-bit TX49 processor core intellectual property. NEC Corporation developed the chip's large-scale gate-array technology, and Kyocera Corporation developed highly reliable packaging suitable for use in space. NASDA plans to use the chip in satellite applications, beginning with the Engineering Test Satellite VIII, which will establish and verify the world's largest geostationary satellite bus technology and the Advanced Land Observing Satellite, which will be used for cartography, regional observation, disaster monitoring and resource surveying. "Space applications are among the most demanding of all; performance, power, and stability all are paramount. We are, of course, delighted that HIREC demonstrated their confidence in the MIPS architecture and chose our licensee Toshiba for this critical application," said John Bourgoin, chairman and CEO of MIPS Technologies. "Toshiba and MIPS Technologies have a 10-year history of collaboration in the development of 32- and 64-bit high-performance processor solutions in a variety of embedded applications, including the digital consumer and automotive markets." "The use of MIPS-based technology in the TX49 core, incorporated into a rigorous space-based project, underscores the broad applications of the MIPS architecture and the TX49," said Masahiko Ono, technology executive of the Semiconductor Company for Toshiba Corporation. "We expect that the core nurtured through our joint development efforts has applications for other markets."

Orbiting Earth In Search Of Failure
Huntsville - Jan. 27, 2001It's a mission where failure will be success -- and that's exactly what NASA engineers are hoping for. They anticipate failures in six experiments on the NASA Space Radiation Electronics Testbed, a payload now orbiting Earth aboard the Space Technology Research Vehicle-1-d. The satellite was launched Nov. 15 on an Ariane 5 rocket from French Guiana.
