MIPS Technologies' Highest-Performance 32-Bit Processor Core Families Supported by MontaVista Linux

MontaVista’s Linux Development Platform Helps Customers Quickly Get to Market with Competitive Products for Cost-Sensitive Applications

MOUNTAIN VIEW, Calif., Nov. 22, 2004 - MIPS Technologies, Inc. (Nasdaq: MIPS), a leading provider of industry-standard processor architectures and cores for digital consumer and business applications, and MontaVista Software, Inc., a leading provider of system software platforms, today announced that MontaVista® Linux® Professional Edition 3.1 (Pro) supports the MIPS32® 24K™ and 4KE™ core families.

The 24K cores are the industry's highest-performance 32-bit synthesizable processor cores available for cost-sensitive, high volume applications, while the 4KE core family is one of the most popular MIPS cores for broadband and networking applications. The newer, 625-MHz, 24K core family has experienced the fastest rate of licensing of any MIPS Technologies product line by offering SOC designers the performance, flexibility and support to create highly competitive products with speed, ease and efficiency. With MontaVista Linux Pro 3.1, companies building MIPS-Based™ devices can take advantage of a comprehensive, fully integrated embedded Linux operating system and graphical development environment.

"MontaVista Software has long been committed to providing commercial-grade development platforms for high-performance, low-power MIPS processors such as the popular 24K family of cores," said Scott Jaffe, vice president of business development at MontaVista Software. "Together, we can help our customers create highly differentiated products and get them to market faster with lower overall development costs."

"Linux is becoming increasingly popular among application developers. MontaVista Linux, together with the 24K cores, offers a compelling solution for the many customers who face the challenges of high performance and low system cost," said Jack Browne, vice president of worldwide sales at MIPS Technologies. "The outstanding customer response to the 24K family of cores is due in part to the support of leading third parties in the MIPS ecosystem, and we are delighted to count MontaVista Software among them."

About the MIPS32 24K Family
The MIPS32 24K core family is targeted at high-volume applications such as broadband access, wireless, networking, digital television and office automation. It includes the 24Kc™, 24Kc Pro, 24Kf™ and 24Kf Pro versions. The 24K cores, which are synthesizable, can be targeted by customers at various process nodes: in TSMC's 0.13G process they can exceed 400 MHz, and in the high-performance 0.13 LV-OD low-K process, they can exceed 625 MHz, the highest frequency available in a 32-bit synthesizable core for embedded markets. Designers have the flexibility to optimize for speed, area or power to obtain 2.8mm2 core-only size, 0.58 mW/MHz, or up to 900 Dhrystone 2.1 MIPS performance. In addition, the 24K family offers the highest known Java performance in the SOC industry, or 5000 Embedded CaffeineMark 3.0 at 625 MHz. It also offers, in the 24Kf core, an integrated, high-performance IEEE 754-compliant floating point unit previously found in the MIPS64® 20Kc™ and 5Kf™ cores, which has a certified EEMBC Basic floating-point score of more than 1300 Iterations/MHz.

Development support includes tailored SOC design methodologies from Cadence, Magma and Synopsys, an OCP interconnect structure, and standard libraries and on-chip memories from leading companies that help speed time-to-market. MIPS16e™ code compression technology reduces memory requirements, providing significant savings in overall system cost.
