MIPS Technologies, Inc. Enhances Architecture to Support Growing Need for IP Re-Use and Integration.

MOUNTAIN VIEW, Calif.--(BUSINESS WIRE)--May 3, 1999--

New MIPS32 and MIPS64 Architectures Combine Best of

Existing 32- and 64-bit ISAs to Create a Stronger

Foundation for Embedded Developers

MIPS Technologies, Inc. (Nasdaq:MIPS) today announced an evolution of its architectural framework for MIPS(R) processors.

The new MIPS32(TM) and MIPS64(TM) architectures incorporates previous MIPS(R) instruction set architectures, or ISAs, add new more powerful instructions, and expand the MIPS(R) standard to include privileged mode and kernel operations used in operating system software.

These two new standards represent the foundation for all future MIPS(R) processor related development while supporting all legacy IP (intellectual property). They have been defined as part of the company's strategy to address two key issues facing embedded developers: IP re-use and system-on-chip integration.

"These new architecture definitions should strengthen MIPS Technologies' position in the high performance embedded market," said Tom R. Halfhill, a senior analyst at MicroDesign Resources, which publishes the Microprocessor Report.

"By combining the best parts of the existing MIPS(R) instruction sets with some very useful extensions, the MIPS32(TM) and MIPS64(TM) architectures provide new options to embedded-system designers who need high performance in a customizable processor.

"Both architectures should be well suited for system-on-a-chip solutions. MIPS Technologies is obviously positioning itself to take advantage of the emerging markets for new kinds of low cost information appliances and personal computing devices."

Developer tool vendors will clearly benefit from the new standards. The new architectures simplify and standardize the underlying mechanisms used in supporting real-time software, and it enables vendors to efficiently craft a single set of development tools that support MIPS-based(TM) processors. This will lower the cost and speed the development of new tools for the MIPS(R) processor market.

"As the leader of the MIPS(R) architecture alliance, we must ensure that the market has the standards it needs to support growth," said Lavi Lev, senior vice president of engineering for MIPS Technologies, Inc.

"These new architectures provide a powerful and stable platform to supports high performance 32-bit embedded applications and provide a seamless upgrade to the 64-bit level. They lower the cost of developing MIPS-based(TM) systems and enable the reuse of hard-earned development expertise across multiple designs."

The new MIPS32(TM) and MIPS64(TM) architecture standards build on 15 years of MIPS(R) processor experience. During this time, the MIPS(R) architecture has become the leading embedded 32-bit and 64-bit RISC architecture because of its robust instruction set, extensible architecture, its scalability from 32-bits to 64-bits and the widespread support from numerous licensees of MIPS Technologies.

The original MIPS I(TM) ISA has evolved into the MIPS II(TM), MIPS III(TM), MIPS IV(TM) and MIPS V(TM) ISA levels. MIPS Technologies, Inc. has taken advantage of the experience from the past 15 years and developed the new MIPS32(TM) and MIPS64(TM) architectures.

The MIPS32(TM) architecture incorporates all of the 32-bit MIPS I(TM) and MIPS II(TM) ISAs with the addition of features from popular 64-bit R4000(R) and R5000(R) processor families. These include conditional moves, prefetch instructions, privileged instructions and other enhancements.

In addition, DSP enhancements such as multiply (MUL) and multiply and add (MADD) instructions have been standardized and added to the new architectures. While these instructions have been available as licensee-specific extensions in the past, this is the first time that they have been available as a standard part of the MIPS(R) architecture.

The MIPS64(TM) architecture incorporates the latest MIPS V(TM) 64-bit ISA with the addition of the standardized MADD and MUL instructions. MIPS64(TM) provides full support of 64-bit floating point co-processors and support for flexible instruction and data caches.

It is a superset of the MIPS III(TM), MIPS IV(TM), and MIPS V(TM) ISAs. In addition, it adds a MIPS32(TM) mode so that all MIPS32(TM) code will run on a MIPS64(TM) architecture platform. This ensures upgrades from 32-bit to 64-bit processors are fast and seamless.

This simplifies the task of upgrading systems from 32-bit to 64-bit operation, enables reuse of intellectual property and ensures interoperability for the future. The MIPS64(TM) architecture is well-suited for applications that need to process large databases and streaming data types such as audio and video.

Both architectures include a consistent privileged mode and cache access control mechanisms. One of the advantages of the MIPS(R) architecture is flexible cache configurations that let developers choose the most appropriate cache implementation based on system performance requirements, power constraints and component costs.

These new cache control instructions make cache implementations consistent and easier to manage, and development of real-time operating system software is simpler. Development tool vendors can now develop one set of kernel software for use across many platforms. This reduces the development time and cost of supporting multiple MIPS(R) processor implementations.

The first implementations of the new architecture are the MIPS32(TM) 4Kc(TM) (code named Jade) core licensed by Texas Instruments (see press release dated 2/16/99), and IDT's RC32364(TM). Later this year, the MIPS64(TM) 20K(TM) family (code named Ruby) will be available.
