MIPS Technologies Announces Highest Performing 32-Bit Core Family in the Embedded Industry

MIPS32™ 24K™ Core Family Features 550 MHz Optimized Design Flows and System-Level On-Chip Interconnects

SAN JOSE, Calif, Microprocessor Forum - October 13, 2003 - MIPS Technologies, Inc. (Nasdaq: MIPS, MIPSB), today unveiled details of the highest performing 32-bit synthesizable core family within the embedded market. The disclosure of four new cores, derivatives of the recently introduced MIPS32™ 24K™ microarchitecture (see press release dated June 16, 2003), will help engineers quickly achieve their SOC design goals by offering a proven path to silicon through optimized front-to-back end methodologies and industry-standard on-chip interconnects.

MIPS Technologies also introduced a new version of its SOC-it™ system controller. Called SOC-it OCP, this version is optimized for the OCP on-chip interconnect technology developed as the native interface for all 24K cores. OCP-IP (www.ocp-ip.org) defines a high bandwidth point-to-point interconnect that addresses the performance needs of next-generation SOC designs. The SOC-it system architecture solution provides an integrated high performance memory controller (SDR and DDR) and bridging solutions to other bus standards. By coupling the SOC-it OCP with 24K cores, MIPS Technologies delivers dramatic time-to-market reductions to customers by pre-engineering the highest performance common system components.

Market Demand for High Performance, Programmability
System companies are under increasing pressure to reduce product costs while incorporating more features and functionality into next-generation SOCs. To keep ahead of this "product treadmill," engineers are turning to high performance, programmable processors to give a design more headroom so that future upgrades can be implemented in software to reduce the need to develop new silicon. The MIPS32 24K core family is ideal for these types of performance driven applications, such as integrated digital television, set-top box and DVD devices, which require high performance microprocessors to deliver an optimized user experience.

"SOC designers can use the synthesizable 24K core family to take full advantage of the highest frequency available in 32-bit cores and differentiate their products," said Mike Uhler, chief technology officer for MIPS Technologies. "To minimize the system-level design effort, we have teamed with industry-leading companies to provide customers with tailored design flows and optimized libraries, memories and bus interconnects. Furthermore, our SOC-it system controller is optimized for OCP to reduce the design requirements by providing pre-validated system level integration."

Features of the MIPS32 24K Core Family
As with all MIPS-based™ technologies, the 24K core family offers broad tool and software support only available to products based upon an industry-standard architecture. There are four 24K cores that offer a variety of configurations to support customer requirements. All cores include Release 2 features of the MIPS32 architecture that support multiprocessing, enhanced bit-field manipulation, reduced interrupt latency and enhanced cache control.

Each core is designed to serve the performance driven needs of the broadband access, office automation and digital consumer markets, and features a range of options from user extendable instructions to floating point configuration.

• 24Kc™ core: Base version incorporating an eight stage pipeline that is optimized for high performance. Includes a 32x32 Multiply/Divide Unit and configurable memory management unit with TLB or fixed mapping. Ideal for next-generation control plane applications.
  
  
• 24Kf™ core: Includes hardware floating point support that is fully compliant with the IEEE 754 standard. Floating point is a key component of several major applications.
  
  
• 24Kc and 24Kf Pro™ versions: Enabled with user extendable instructions, featuring the CorExtend™ capability. This facilitates optimization of algorithms for data-plane style processing within a programmable environment. CorExtend technology is fully compatible with the industry-standard MIPS32 architecture, so full tool chain support is maintained.

"We're going to great lengths to ensure 24K licensees will achieve 400 to 550 MHz worst case in mainstream 0.13um technologies in a small silicon foot print and within the constraints of tight development schedules," said Victor Peng, vice president of engineering for MIPS Technologies. "Companies that introduce products with more capabilities into the marketplace first have a tremendous benefit over their competitors. And we intend to give 24K licensees a significant performance and time to market advantage."

24K Core Family Support by the MIPS® Ecosystem

Cadence Design Systems
MIPS Technologies and Cadence Design Systems have collaborated to deliver a comprehensive Cadence Encounter RTL-to-GDSII reference flow for the synthesizable MIPS32 24K core family. The highly automated flow includes global synthesis, placement, routing, timing analysis and verification-providing 24K core customers with a fast, predictable path to silicon. MIPS Technologies specifically chose Cadence Encounter RTL Compiler for synthesis because of its superior quality of silicon (QOS) results.

"Quality of silicon is critical to our customers," said Jan Willis, vice president of strategic third-party programs at Cadence. "As a result of design chain collaboration with MIPS Technologies, the Cadence Encounter RTL-to-GDSII flow provides MIPS32 24K customers a rapid way to get the best silicon."
