MIPS32® 24Kc Core plus Virage Logic Memories and Standard Cells Enable High-Speed SoC Designs for Portable Consumer and Communication Devices
MOUNTAIN VIEW and FREMONT, Calif., Jan. 19, 2005
MIPS Technologies, Inc., (Nasdaq: MIPS), a leading provider of industry-standard processor architectures and cores for digital consumer and business applications, and Virage Logic Corp. (Nasdaq: VIRL), a leading provider of semiconductor intellectual property (IP) platforms, today announced that they have produced a fully-routed design that they believe provides the lowest cost, lowest power processor available today at 333 MHz. The combination of the MIPS32® 24KcTM cores high performance and low power with Virage Logics small footprint standard cell logic and memory IP results in an excellent choice for portable consumer and communication devices.
Using a MIPS32 24Kc core plus Virage Logics Area, Speed and Power (ASAP) Logic High-Density (HD) libraries and ASAP Memory HD memories in a TSMC 0.13G process, the companies have produced a tape-out ready design for a 333 MHz processor in 3.7 mm2, consuming 166.5 mW and delivering 480 Dhrystone MIPS (DMIPS) performancea 34% smaller core consuming 37% less power and delivering 20% higher performance than an ARM 1136J-S running at 333 MHz. Portable consumer applicationsfor which this combination is particularly well suitedwill increasingly rely on Java-based applications. The fully-routed 24Kc core with Virage Logic libraries and memories delivers 2,664 CaffeineMarks at 333 MHz.
The MIPS32 24Kc core delivers, we believe, the most outstanding combination of high performance, low cost, and low power of any core in the market, said John Bourgoin, MIPS Technologies president and CEO. Virage Logics memories and standard cells are the smallest, highest performance, lowest power available. With this combined technical advantage, designers benefit from the high performance while minimizing power consumption and die size, extending battery life and reducing manufacturing costs. We think this is the best value proposition in the market today for portable consumer applications.
Were very pleased with the impressive results of this collaborative effort, said Adam Kablanian, Virage Logics president and chief executive officer. Consumer devices now make up over half of the $1.3 trillion global electronics market, with portable consumer and communication products making up a growing part of that. The combination of MIPS cores and Virage Logic IP enables engineers to greatly reduce development and system costs, power consumption, design uncertainty, and time-to-market. They come out ahead in the three areas that matter most price, performance and power and that provides a key competitive advantage.
The MIPS architecture has key design wins in a range of portable consumer applications. OEMs shipping MIPS-Based portable consumer applications include Canon, Casio, Fujifilm, Fujitsu, JVC, Minolta, PENTAX, Philips, Samsung and Sony. MIPS32 24Kc Core with Virage Logic IP Provides a More Cost-Effective Solution
Below is a comparison between the MIPS Technologies 24Kc core and the ARM Holdings ARM1136J-S core. The 24Kc core referenced below was implemented from released RTL using Virage Logics ASAP Logic HD libraries and ASAP Memory HD memories and without voltage scaling techniques that can further reduce power consumption.

The combination tested was a MIPS32 24Kc core with 16K instruction and 16K data caches, Virage Logic ASAP Memory HD memory and ASAP Logic HD cells compared to an ARM1136J-S, using the performance characteristics posted on ARMs web site as of 1/18/05. The results include all logic, including memory management, cache control and debug on TSMCs 0.13G process; core area with cache includes the core, a 16KB instruction cache and 16KB data cache and all necessary RAM. The numbers quoted for both cores represent fully routed layouts including power-rails and scan insertion. Java performance results are based upon direct compilation using an Esmertec FastDAC direct Java compiler for the MIPS32 24Kc core. About the MIPS32 24K Core Family
The 24K core family 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 TSMCs 0.13G process the cores exceed 400 MHz, and in the high-performance 0.13 LV-OD low-K process, they will exceed 625 MHz, the highest frequency available today in a 32-bit synthesizable core for embedded markets. Designers have the flexibility to optimize for speed, area or power. In addition, the 24K core 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, which has a certified EEMBC Basic floating-point score of more than 1300 Iterations/MHz.
Development support provided with the cores includes tailored SOC design methodologies from Cadence, Magma and Synopsys, and an OCP interconnect structure. MIPS16e code compression technology reduces memory requirements, providing significant additional savings in overall system cost.
The MIPS32 24K cores have been licensed to fourteen companies. Publicly announced licensees include Atheros, Kawasaki Microelectonics, LSI Logic, Micronas, PMC-Sierra, Realtek, Scientific Atlanta and TZero. About Virage Logic's ASAP Logic and ASAP Memory Products
