It's been a while since we last heard from CSR, but that changed earlier this week, when the company unveiled its new SiRFprimaII and SiRFusion platforms, alongside its SiRFstarV architecture. According to the UK-based firm, both SiRFstarV and SiRFusion are designed to provide more accurate geographic data and enhanced indoor navigation capabilities across PNDs and other mobile devices. SiRFstarV, the logical follow-up to CSR's SiRFstarIV architecture, culls location data not only from GPS, but from Galileo, Glonass and Compass satellites, as well as a range of radio signals, accelerometers, gyros and compasses. All this information is fed to the user via the SiRFusion platform, which combines data from radio systems and sensors to provide constantly updated location graphics. Together, both SiRFstarV and SiRFusion promise to help users find their way around both indoor and outdoor locales, within an accuracy range of ten to 15 meters.
The SiRFprimaII platform, displayed above, is strictly geared toward in-car navigation and infotainment systems. This system combines a SiRFprimaII SoC and TriG RF multi-GNSS radio with CSR's Bluetooth and WiFi technologies to create a multimedia rich, touchscreen-based in-car environment. Geared toward both ODMs and OEMs, this hardware-software combo enables drivers to get more reliable navigation data, while allowing passengers to stream video, surf the web and manipulate everything via remote control. As for that SoC, it's powered by a 1GHz ARM Cortex A9 app processor, features an LCD controller for displays of up to 1280 x 720 resolution, and boasts a pair of 3D graphics and video accelerators.
