SiRFSoft mobile GPS software is a new approach to multimode GPS signal processing for wireless handheld devices. It is designed to deliver scalable, superior positioning performance without the need for a dedicated GPS baseband integrated circuit. Compatible with major cellular standards, SiRFSoft harnesses the processing power available in application processors to greatly reduce the footprint and cost of location-enabling mobile wireless devices.

Targeted at Intel XScale® Technology based and OMAPI compatible platforms, SiRFSoft uses flexible, high-performance GPS signal acquisition algorithms to deliver fast, coherent processing of weak GPS signals (up to -159 dBm) for robust operation, as well as fast acquisition (3-5 sec) of strong and medium-strength signals. Incorporating SiRF’s proven multimode location architecture, SiRFSoft automatically adapts to utilize whatever network assistance data is available, including GSM (04.31), UMTS (25.331), CDMA (IS-801), ARIB W-CDMA and PDC, and is able to obtain fixes autonomously when no aiding is available. As a result, SiRFSoft is designed to achieve excellent location determination - affordably.
