Broadcom Announces New GNSS chip destined for smartphones, tablets or autonomous GPS (NDP) units, with location within the bonus...
Broadcom announces its new controller multi-constellations for the reception of signals from several positioning systems satellite, grouped under the acronym for Global Navigation Satellite System GNSS.
This new chip is the number BCM4752 and supports the US system GPS, but also its Russian declination GLONASS or QZSS Japanese system. To improve the accuracy of the positioning signal, Broadcom adds to its smart SBAS (Satellite-Based Augmentation System) system that encompasses several standards of correction of the positioning as WAAS to the United States or to the EGNOS for Europe.
In addition to the support of these many satellite positioning systems, Broadcom provides that navigation assisted its chip will allow a faster first acquisition point positioning in said "cold" startup or detection of tunnels even faster for a follow-up of ultra navigation States, not to mention the problem of positioning in the city (called also problem of the canyon urban because of large buildings that frame the) (Street).The use of GNSS also provides a location within buildings using nearly 59 satellites that orbit our planet. Without however that it works in all types of buildings.

In addition, Broadcom worked on a mode ultra-basse consumption for a location in real time or at regular intervals for the "geofencing" used for alerts or the configuration of the mobile with its location. For example a passage in vibrator mode and display of appointments at the arrival to the Office or display a reminder from the Office or automatically turn on WiFi and enter mode ringtone in coming home.This new BCM4752 chip also passes to 40 nm engraving, which could, according to the manufacturer, reduce the consumption of the order of 50% and size for better integration in mobile terminals in addition in most. Production of this chip should intervene at the earliest with test versions already sent to partners of the constructor.
The HB-VD904 mini-PCIe full HD video hardware decoder is based on Broadcom's BCM70010/BCM70012 Crystal HD chipset. It supports real-time decoding of a single stream HD AVC/VC-1/MPEG-2/H.264 video. This add-on decoder enables most Intel Atom based PCs, netbooks and digital signage players to playback high definition video files and streaming media up to 1080p resolution. With less than 2W of power usage, this high performance and low power consumption solution reduces CPU utilization and enhances mobile and industrial platform designs. The HB-VD904 supports formats like VC-1, WMV9, WMV-HD, H.264, MPEG-2 format in any compliant resolution from QVGA up to 1920 × 1088.
The HB-VD920 mini-PCIe full HD video hardware decoder is based on Broadcom's BCM70010/BCM70015 Crystal HD chipset. It supports real-time decoding of a single stream HD AVC/VC-1/MPEG-2/H.264 video. This add-on decoder enables most Intel Atom based PCs, netbooks and digital signage players to playback high definition video files and streaming media up to 1080p resolution. With less than 2W of power usage, this high performance and low power consumption solution reduces CPU utilization and enhances mobile and industrial platform designs. The HB-VD920 supports formats like VC-1, WMV9, WMV-HD, H.264, MPEG-2, DivX, XviD format in any compliant resolution from QVGA up to 1920 × 1080.
