MOUNTAIN VIEW, Calif.--(BUSINESS WIRE)--April 5, 2004

Customers Already Leveraging the MIPS32(R) 24K(TM)

Core Family For Next-Generation Wireless, Consumer,

Automotive and Office Applications

MIPS Technologies, Inc. (Nasdaq:MIPS) today announced that the highest performing 32-bit synthesizable processor core family in the embedded market has been released for general availability and licensing by OEMs and semiconductor companies. To date, the MIPS32(R) 24K(TM) core family has experienced the fastest early rate of licensing of any MIPS Technologies' core in the company's history. The product family is targeted at high-volume market applications such as broadband access, wireless, networking, digital television and office automation. Silicon based upon customer implementations of the 24K family is expected to enter the market by the end of calendar year 2004.

The 550 MHz 24K family is ideally suited for performance-hungry applications and cost-sensitive markets, and offers 1.44 Dhrystone MIPS/MHz performance in a core area of less than 3.0 mm(2), along with a wide range of configurable features. At the same time, it offers SOC designers broad tool and software support that minimizes development time, risk and cost. Development support includes tailored, front-to-back-end design methodologies and a standard, Open Core Protocol (OCP) interconnect structure. The core family also was designed to be implemented using standard high-performance libraries and on-chip memories from industry-leading companies.

"Since we introduced the 24K microarchitecture just a few quarters ago, we have seen extraordinary interest and demand for the first products," said John Bourgoin, president and CEO of MIPS Technologies. "The combination of high performance in a flexible, synthesizable core coupled with a low system cost point is clearly appealing. We also are pleased with the growing list of leading third parties within the MIPS ecosystem that are optimizing their product offerings for SOC designers and software developers using the 24K core family."

"Performance-driven, cost-sensitive applications will benefit significantly from high performance products such as the 24K core family. It offers SOC designers the headroom needed to create competitive and differentiated products, while giving them the tools to get to market with speed, ease and efficiency," said Tony Massimini, chief technologist at market research firm Semico Research.

Performance Headroom

The 24K cores are ideal for engineers who need to keep costs down while adding more features and functionality to next-generation SOCs. High-performance, programmable processors give a design more headroom so that future upgrades can be implemented in software. The 24K cores also offer the features and flexibility to meet the needs of today's most demanding applications. For example:

-- Automotive Telematics systems, which provide multi-function

features such as car navigational systems, satellite radio and

DVD players, often require multi-OS environments running

simultaneous, real-time applications. The 24K family delivers

the high performance and programmable features that meet these

needs and those of next-generation systems, such as Internet

browsing.

-- Broadband service providers are targeting higher-speed and

value-add services such as improved network security,

voice-over-IP (VoIP) and video-on-demand, which require higher

processing performance and system optimization. In WiFi

networking, higher data rates and new features are routinely

implemented before standards are solidified, so high

performance and flexible microprocessors are required. The 24K

family offers superior performance for higher data rate

services, flexible solutions for changing standards, and

customizable CorExtend(TM) instructions to enable highly

differentiable, low-cost solutions.

-- DVD systems require uncompromised performance at an attractive

price point to run high-impact applications and system level

services such as audio jukebox, digital photo archive, digital

TV reception, DVD recording/navigation stacks, digital rights

management systems, and multi-format audio video playback and

record. The 24K family offers an OCP interface for fast SOC

integration, fine grain clock gating to reduce power

consumption, and the CorExtend capability and architectural

enhancements to maximize system performance and resources.

-- Set-Top Boxes and Interactive Digital TVs are required to

perform more and more functions simultaneously, support

ever-changing standards, offer security features, and run

Java. The 24K family has the performance headroom to offer

field-upgradeability and accommodate new standards, and was

designed to power through Java, graphics and demanding

applications with features such as an ultrafast multiply,

floating point support and the CorExtend capability.

Key Features

The number one feature of the 24K family is high performance. To yield high frequency, the 24K family is based on an 8-stage pipeline. A full cycle is allocated to the instruction and data cache access to enable performance scalability across a wide range of technologies. Sophisticated hardware branch prediction is present to keep the pipeline supplied with instructions. The memory subsystem was designed with high performance in mind. Four load misses may be outstanding and are processed by a 64-bit connection to the OCP interface standard.

The 24K core interface is standardized on OCP on-chip interconnect technology defined by the Open Core Protocol International Partnership (OCP-IP). Designers who choose to utilize OCP can build their cores independent of specific bus protocols and easily reuse OCP-compliant cores across multiple SOC designs, thus reducing development time and lowering risk and costs. They also can take advantage of MIPS Technologies' SOC-it(TM) system-level controller optimized for OCP. The SOC-it OCP controller provides a tightly coupled memory controller and includes a bridge to other on-chip system buses, thus reducing subsystem memory latency and increasing system throughput.

Specifications:

Process             0.13-micron

Frequency           400-550 MHz (worst case)

Performance         576-792 Dhrystone MIPS

Core size           less than 3.0 mm(2) for a 24Kc(TM) core

All four cores in the 24K family include Release 2 features of the MIPS32 architecture, such as enhanced bit-field manipulation and reduced interrupt latency. Support for the MIPS16e(TM) code compression extension is standard. Because the product family is synthesizable and highly configurable, users can tune for performance, area or power to optimize the core for their particular design application. For example, they can specify the primary cache sizes, style of memory management unit, level of debug facilities and amount of clock gating.

-- 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.

-- 24Kf(TM) core: Includes fully compliant IEEE 754 hardware

floating point support at reasonably low cost, requiring less

than 1.0 mm(2) of additional area in a 0.13 micron process.

-- 24Kc Pro and 24Kf Pro core versions: Offer user defined

instructions, featuring the CorExtend capability, to

accelerate processing. For example, it facilitates the

optimization of a wide number 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.
