MIPS Technologies' Multi-threading and DSP Solutions Supported by Green Hills Software's Development Tools

Application Development Environment Offers Quick Time-to-Profit for Licensees of Revolutionary MIPS32® 34K™ and 24KE™ Core Families

Embedded Systems Conference, San Jose, CA, April 4, 2006 - MIPS Technologies, Inc. (NASDAQ: MIPS), and Green Hills Software, Inc., today announced that Green Hills Software's comprehensive set of software development tools for embedded applications supports the latest MIPS® processor cores: the MIPS32® 34K™ family, a revolutionary multi-threading solution for embedded applications, and the MIPS32 24KE™ family, which features the highest performance available in a 32-bit synthesizable core, together with an integrated DSP capability.

Green Hills Software's fully integrated, end-to-end MULTI® Integrated Development Environment (IDE), which is optimized for the MIPS32 and MIPS64® architectures, enables MIPS licensees and end users of 34K and 24KE core-based systems to rapidly develop, debug, and optimize code, and significantly reduce development costs and time-to-market.

"MIPS Technologies has done it again with its new multi-threading and integrated DSP capabilities. Developers who want to take advantage of these remarkable new cores can quickly reap the performance, power and cost benefits by using the best development environment available for MIPS processors," said Mike Wolf, general manager of advanced products at Green Hills Software.

"Developers who are trying to keep up with the insatiable demand for higher throughput, lower system cost and lower system power by integrating new, leading-edge technologies such as multi-threading, can do so without compromising productivity, thanks to the MIPS Ecosystem and the support of leading tools providers such as Green Hills Software," said Jack Browne, vice president of marketing at MIPS Technologies. "Green Hills' MULTI IDE offers developers a best-in-class environment for quickly and easily designing and deploying their MIPS-Based products."

In addition to the 34K and 24KE core families, Green Hills' MULTI IDE supports the MIPS32 24K®, 4KE™, 4K®, and 4KS™ core families. It also supports MIPS-Based™ processors developed by MIPS Technologies licensees including AMD, Broadcom, IDT, LSI Logic, NEC, PMC-Sierra, QuickLogic and Toshiba.

Other Green Hills Software development tools available for MIPS-Based applications include the INTEGRITY® RTOS, a secure, royalty-free real-time operating system for mission-critical embedded applications, which currently supports the MIPS32 4K family. Support for the 24K and 24KE families is now underway and is expected to be announced this summer.

About the MIPS32 34K Family
The MIPS32 34K core family is a revolutionary multi-threading solution for high-performance, cost-sensitive embedded applications. Implementing the MIPS® MT ASE, it processes multiple software threads in parallel, masking the effect of memory latency to deliver significant gains in system performance and cost savings, with a very modest increase in die size. Internal benchmarks indicate that the 34Kc™ core running just two threads achieved a 60-percent speed increase over a single-threaded processor with only a 14-percent increase in area. In addition, the 34K core family leverages the high-performance 24KE microarchitecture, which includes the MIPS DSP Application Specific Extension (ASE) for developers who want the benefits of an integrated DSP capability.

About the MIPS32 24KE Family
The MIPS32 24KE core family leverages the high-performance 24K™ microarchitecture and the MIPS DSP ASE to provide a very efficient DSP capability while significantly reducing overall SoC die area, cost, and power consumption. The DSP instructions in 24KE cores improve signal processing performance up to 3x over a range of embedded applications when compared to RISC implementations without the DSP ASE.
