CEVA and GSN to offer software-based GNSS solutions
Oct 31, 2012 (Datamonitor via COMTEX) --
CEVA, Inc., a licensor of silicon intellectual property platform solutions and DSP cores, and Galileo Satellite Navigation, Ltd., or GSN, a developer of multi-system global navigation satellite system, or GNSS, receiver technology, have announced a partnership to offer software-based GNSS solutions for the CEVA-XC and CEVA-TeakLite-III DSP platforms.
GSN's software-based approach to satellite receivers enables SoC developers to incorporate advanced GNSS navigation functionality into their designs, with virtually no effect on performance, area and cost, and with no use of hardware acceleration.
Illustrating this, GSN's GNSS receiver consumes 5% of the available MIPS on a CEVA-XC323 DSP, enabling it to run concurrently with a range of other air interfaces on the same processor, including LTE, LTE-Advanced, Wi-Fi and Bluetooth, as well as smart grid protocols. The CEVA-TeakLite-III software-based implementation reportedly enables a cost- and power-efficient GNSS solution for mobile and automotive devices.
The GSN GNSS receiver running on a CEVA DSP consumes power - as low as 10mW in a 40nm process - and has the ability to work in lower rates, or snap-shots for ultra-low-power mobile scenarios. The solution delivers a tracking sensitivity of -165 dBm, offering a GNSS experience in challenging environments.
"GSN's software-based approach for satellite receivers perfectly complements our DSPs, offering customers the ability to add GNSS capabilities to any CEVA-powered SoC design," said Eyal Bergman, vice president of product marketing at CEVA. "The availability of GSN's software on our CEVA-XC DSP further reinforces the strength of our software defined radio (SDR) modem strategy for advanced communications."
