SiRF GPS IP Powers New Renesas Automotive System on Chip

Enables OEMs to Create Higher Integration, In-Dash Navigation and

Telematics Systems More Quickly and at Lower Cost

    SAN JOSE, Calif., May 31 /PRNewswire-FirstCall/ -- SiRF Technology
 Holdings, Inc. ( SIRF), a leading provider of GPS-enabled silicon
 and premium software location platforms, today announced Renesas Technology
 Corp. has licensed SiRF GPS baseband IP blocks to location-enable its new
 SuperH(TM) Family SH7775, an SoC (system on chip) solution designed for
 high-performance car information systems (CIS). With its embedded SiRF GPS
 capabilities, the Renesas SH7775 will provide automotive OEMs and their
 Tier-1 suppliers worldwide with a solid foundation for building the next
 generation of affordable in-dash navigation, telematics and auto
 information systems, and offers SiRF entry into the lucrative automotive
 market in Japan and elsewhere through its partnership with that country's
 leading in-vehicle platform supplier.
     The SiRF IP solution delivers superior GPS performance for automotive
 applications, and achieves significant system cost savings through greater
 integration and by making optimum use of the SH7775's SuperH RISC engine
 and memory resources. Along with a standalone SiRF GRF3i+ radio frequency
 subsystem IC, the embedded SiRF GPS technology handles all the
 time-critical aspects of obtaining location measurements from the GPS
 satellites, and passes the raw positioning data to SiRFNav GPS software
 running on the SH-4A processor core. SiRF will directly provide the RF
 subsystem and system-level integration support to automotive OEMs and
 Tier-1 suppliers to ensure successful integration of the Renesas SH7775
 solution into their products, maintain compatibility and interoperability
 of the GPS and other host platform functions and obtain optimal GPS
 performance.
     "From a strategic perspective, our partnership with Renesas is
 important because it provides us with an opportunity to significantly
 enhance our market position in the in-car navigation and telematics systems
 and to gain critical insights into future market needs and trends," said
 Kanwar Chadha, founder and vice president of marketing for SiRF.
 "Automotive OEMs and their Tier-1 suppliers can now have the market proven
 GPS technology integrated in a cost- effective automotive system platform
 from the two market leaders with a worldwide support infrastructure."
     Chadha noted that today's announcement is part of a natural progression
 of a deepening relationship between SiRF and Renesas Automotive Business
 Unit. In October 2004, SiRF announced it was chosen by Renesas as the GPS
 technology provider to location-enable the COMET(TM) Biscayne automotive
 telematics platform, bringing world-class, host-based GPS capabilities to
 the COMET reference design. Currently, SiRF is also a member of the SH-Navi
 Consortium, a resource group developed by Renesas to help automotive OEMs
 and Tier-1 suppliers find solutions to CIS software development problems
 and encourage partnerships between the companies involved in the CIS
 market.
     "SiRF is an important global technology partner, and their leading
 position in the worldwide GPS market will be an essential competitive
 advantage for us as we seek additional business opportunities outside of
 Japan, especially in North America and Europe, and the emerging markets in
 Asia," said Tsutomu Miki, general manager, automotive semiconductor
 business unit at Renesas Technology Corp. "By partnering with SiRF, we are
 able to deliver to our customers a highly robust and cost-optimized GPS
 solution ideally suited to creating fully integrated navigation and
 telematics systems for mainstream automotive applications."
     Renesas SH7775 SoC customers will also have the option of employing
 SiRF's tightly coupled dead-reckoning software option, SiRFDrive, for
 vehicle applications requiring continuous and highly accurate position
 information in all environments. Replacing the standard SiRFNav software,
 SiRFDrive software combines GPS and dead reckoning measurements to provide
 continuous and accurate navigation in even the most challenging operating
 environments, such as in covered parking lots, tunnels and in urban
 canyons. This dead reckoning data optimizes and cross-checks the GPS
 function, resulting in the most accurate location solution available today
 for automotive applications.
     The Renesas SH7775 SoC incorporates the SuperH Family's top-end SH-4A
 CPU core capable of 1-GIPS and 4.2-GFLOPS processing performance, and
 integrates many comprehensive peripheral functions required by car
 navigation systems. In addition to the SiRF GPS baseband processing
 capabilities, these include a newly developed graphics engine optimized for
 map drawing, a 3D graphics engine for high-level drawing processing, an
 ATAPI interface, a USB v2.0 host/function interface and a CAN in-vehicle
 LAN interface.
