摘要

Broadcom Corporation of Irvine, California, has released BCM2075, a new, integrated GPS, Bluetooth, and FM radio in a single-chip design, targeting location-based services (LBS) applications. The processor reduces the host and application processing required by competing combo solutions, enabling greater adoption in mass market handsets, according to the company.rnThe BCM2075 integrates four radios (Bluetooth, GPS, FM receive, and FM transmit), enabling the radios to operate simultaneously and with minimal interference.rnThe company expects the chip to drive key handset applications that network operators and consumers are looking to adopt, furthering the cause of LBS and advanced multimedia available on mid-range mobile phones. The GPS core uses a host-based integration architecture that splits the processing duties between the BCM2075 and the host CPU system and provides low GPS power, delivering a reported 50 percent better power performance compared to other chips, the company said. Broadcom's GPS technology, stemming largely from its July 2007 purchase of Global Locate, enables a fast time-to-first-fix and provides integrated support for other positioning technologies, such as Wi-Fi positioning.
