MIPS-Based Chip for Space Applications Developed By HIREC, Toshiba, NEC and Kyocera

WORLD'S FIRST 64-BIT RISC PROCESSOR SOARS INTO SPACE

MIPS-Based Chip for Space Applications Developed By HIREC, Toshiba, NEC and Kyocera

MOUNTAIN VIEW, Calif., March 12, 2001 MIPS Technologies, Inc. (NASDAQ: MIPS, MIPSB), a leading provider of industry-standard processor
architectures and cores for digital consumer and network applications, today announced that High-Reliability Components Corporation (HIREC) of Japan, under
contract with National Space Development Agency (NASDA) of Japan, has developed the first 64-bit RISC microprocessor chip for space applications.

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."

The features implemented by Toshiba to handle the rigors of space and ensure reliable operation include:

MIPS instruction set
36-bit address bus (64-bit virtual address), 64-bit data bus
8KB instruction cache, 8KB data cache with 8-bit error detection & correction
25MHz pipeline frequency
50MHz external clock (a selectable feature for the bus clock rate)
64-bit general-purpose registers, integer unit, floating point registers, and floating point unit
Operating voltage of 3.3V (5.0V I/O tolerance)
Operating temperature of 40 to +85 degrees C
304-pin ceramic flat package
