SiCortex Inc. Licenses MIPS64 Architecture for Low-power, High-performance Teraflop Computing

Thousands of MIPS-Based™ Cores Power Next-generation Linux Systems

MOUNTAIN VIEW, Calif., - December 19, 2006 - MIPS Technologies, Inc. (NASDAQ: MIPS), a leading provider of industry-standard processor architectures and cores for digital consumer, networking, personal entertainment, communications and business applications, today announced that SiCortex Inc. has licensed MIPS Technologies' industry-standard 64-bit architecture for its new generation of high-performance, low-power Linux teraflop computers.

The SiCortex SC5832 is an enterprise-class computer that features more than 5800 MIPS64® processors, eight terabytes of memory, and 2.1 terabits of IO. Using power-efficient MIPS cores enables a system design that will save end users hundreds of thousands of dollars per year in energy costs. More important, it enables extremely dense packaging, which increases delivered performance. This power savings is critical to supercomputer users who can spend more than one million per year in electrical costs and cooling systems alone.

"Teraflop computing is gaining broader acceptance as the IT market continues to face energy and cooling challenges and ever-increasing performance expectations, " said Brad Holtzinger, vice president of worldwide sales at MIPS Technologies. "We're excited to be part of a new generation of SiCortex supercomputers that leverages our low-power capabilities and proven 64-bit architecture."

"With the 64-bit MIPS cores at the heart of our breakthrough cluster computer system, we can provide our customers with the superior level of sustained performance coupled with the low energy consumption they require," said Dr. John Mucci, chief executive officer at SiCortex. "These advantages, along with an installed base that adds hundreds of millions of new units shipped per year and a software ecosystem that has evolved over more than 20 years, made MIPS Technologies the obvious choice."
