SiRF introduces SiRFatlasIV multifunction location system processor
Press release; Meiling Chen, DIGITIMES [Wednesday 10 June 2009]

SiRF Technology has introduced the SiRFatlasIV multifunction location system processor targeting an emerging class of location-centric devices.

With its high-performance location engine and twice the memory bandwidth of current entry-level systems, the SiRFatlasIV platform -available now in production quantities - is designed to minimize bill-of-materials (BOM) and overall system cost, according to the company.

SiRFatlasIV is already in use by several leading OEMs and ODMs, including Asustek Computer/Unihan Technology, Binatone Electronics International, CiREX Technology, Foxconn Technology Group, Globalsat Technology, Maylong's GPS for Dummies, Navigon AG, NDrive Navigation Systems SA, Nextar, Wistron and YF International, according to the company.

This high-sensitivity, 64-channel, multi-satellite system location engine, with more than one million correlators, improves time to first fix (TTFF) in tough environments, and provides true -161-dBm simultaneous tracking of both GPS and Galileo satellites, SiRF said.

The SiRFatlasIV's high sensitivity GPS core also allows the use of lower cost patch antennas and less expensive 2.5 ppm crystal oscillators without impacting performance. .

The SiRFatlasIV provides a 500-MHz ARM11 processor core with vector floating point unit complimented by a 64-bit system bus and a high-speed memory controller with DDR 400/Mobile-DDR 333 memory module support.
