The SiRFstarIIA GPS system on chip is billed as a highly integrated and cost-effective solution for creating affordable automotive navigation and telematics systems.
Software maximises GPS positional accuracy
New GPS/dead reckoning software offers a novel approach to maximising position availability and accuracy for automotive navigation and telematics applications at a significantly lower cost.
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 stand-alone 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", says 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".
The move 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 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", says 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-optimised 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 optimises 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 1GIPS and 4.2GFLOPS 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 optimised 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.
