RFMD has announced the RF8110 software-based GPS that integrates high-performance GPS applications in smartphones, wireless PDAs, digital cameras, gaming devices and other battery-operated mobile devices.

It offers scalable performance depending on the required sensitivity, accuracy and end-user application. It supports push-to-fix, location-based services applications as well as automotive and pedestrian navigation in outdoor and low signal strength environments.

The hardware component is a mixed-signal RFIC built-in 0.18 µm CMOS technology for low power and small size.

It has a hardware accelerator on-chip to offload the system's applications processor and to minimise the data transfer rate to the host CPU. Low power consumption is achieved through various hardware- and software-controlled power save modes.

The GPS software-based architecture allows for the addition of future functions, enhancements and user-specific features on an as-needed basis.

Designed to be used in portable devices, it can be integrated into a variety of host platforms powered by ARM-based applications processors like Intel's XScale processor, Texas Instruments' OMAP, Freescale's i.MX and Samsung's S3C.

It is operating system agnostic and supports a variety of mobile platforms including Linux, Windows Mobile 5.0 and Symbian.

It supports both autonomous as well as standards-based assisted modes of operation.
