(NASDAQ: SIRF), a leading provider of GPS-powered location platforms, todaylaunched its SiRFprima TM multifunction platform to enable the next generation of location-awaremobile devices that significantly enhance the consumer experience for location applications andmedia rich content. The SiRFprima platform combines an industry leading GPS/Galileo locationengine, powerful application processor, rich audio and video recording and playback capabilities,high-resolution 3D graphics and a host of peripheral interfaces – all tuned to operateconcurrently. Supporting both WinCE and Linux operating system environments, the SiRFprimaplatform will give manufacturers greater flexibility to create in a timely and cost-effectivemanner unique, full-featured products that meet consumers’ high expectations for performance,affordability and portability.“With its high-performance multifunction engines all tuned to run in harmony, theSiRFprima platform sets a new standard for performance and integration in the emerging market

SiRF Sets New Course with Multifunction SiRFprima Processor Page 2for exciting new location-aware convergence products,” said Kanwar Chadha, founder and vicepresident of marketing for SiRF. “We believe the SiRFprima platform delivers on our vision ofthe convergence of location with rich media content, and extends SiRF’s leadership in providinginnovative solutions that bring the power of location to the mainstream.”The SiRFprima platform includes an ultra-high-speed, multifunction processor comprisedof an advanced ARM11 core, a high-performance location engine that supports both GPS andGalileo satellite systems and an on-chip DSP. It also includes hardware-accelerated 3D graphicsand multimedia encoding and decoding engines based on the gaming-grade PowerVR MBX 3Dgraphics accelerator core, vertex geometry processor and PowerVR MVED1 videoencode/decode accelerator from Imagination Technologies.The SiRFprima multifunction processor delivers SiRF’s renowned, industry leading,GPS-enabled location performance, featuring 64 channels with -161 dBm sensitivity. Thehardware scalable location engine, with more than 1,000,000 correlators, is among the firstcapable of working with both GPS and Galileo signals simultaneously. Additionally, theSiRFprima processor has been specifically designed to support SiRF’s proprietary GPStechnologies, providing, for example, a dedicated accelerator for the SiRFInstantFixIItechnology.“We are very excited by the SiRFprima platform because it offers an opportunity thatuntil now software developers have only dreamed of. With its overall high performance, from itsgraphics to its memory bandwidth, the SiRFprima platform is definitely the ‘prima’ solution forus,” said Peter Balogh, CTO of Nav N Go, a leading developer supplying navigation applicationsto leading PND players, including the award-winning Nav N Go iGO8 3D navigation software.“With its high degree of integration and extensive array of design features, the SiRFprimaplatform is truly a fantastic advance in the convergence market, and will make it much easier forus to achieve our goal of making navigation and mobile software more accessible and enjoyableto as many people as possible.”The SiRFprima platform supports OpenGL ES, Direct3DM and OpenVG, and can drivefull-color, high-resolution displays with multiple hardware overlay layers. The hardware mediaacceleration has enough processing muscle to encode and decode mainstream and highresolutionvideo standards concurrently with navigation and other operations.

SiRF Sets New Course with Multifunction SiRFprima Processor Page 3In addition to performance gains delivered by the multifunction processor, the SiRFprimaplatform also offers a full complement of peripheral and external interfaces for connecting totouch screens, mass storage devices, video cameras, DVD players, satellite radios and otherdevices.What previously required several external coprocessors has now been integrated into theSiRFprima platform, significantly reducing bill-of-material (BOM) costs for SiRF customers.By integrating typical discrete components onto its own silicon, SiRF not only reduces the totalsystem cost, but also decreases board design complexity and time to market risk.According to a report released recently by New York-based ABI Research,manufacturers of personal navigation devices are facing continued stiff competition and willlikely seek to stand out in the market by adding speech technology, multimedia capabilities, 3Dmap content and other features to their products. ABI Research predicts worldwide sales ofthese convergence devices will surpass more than 100 million units by 2011.Mobile consumer electronics devices – including mobile phones, portable navigationdevices, handheld computers, games and even cameras – have already begun moving beyondtheir original, single-function designs to incorporate numerous combinations of connectivity,location and media and content functions. Mobile phones today routinely offer music playbackand integrated cameras, while portable navigation devices increasingly contain audio, still imageand video playback capabilities and connect wirelessly to mobile phones for hands-freeoperation.SiRF believes the distinctions between some of these product categories will blur as thisconvergence progresses, creating new generations of more powerful multifunctional consumerelectronics devices that navigate, inform and entertain. To compete effectively and satisfyconsumer demand, manufacturers of these convergence products will require more flexible,highly integrated solutions. SiRF believes the SiRFprima platform launched today delivers allthe necessary ingredients and flexibility for developing tomorrow’s premium convergencesystems.
