A software-based GNSS receiver is now available on Tensilica ConnX DSP IP cores, according to an announcement by Cadence Design Systems and Galileo Satellite Navigation, Ltd. (GSN), a developer of multi-system GNSS products including software receiver technology. The core is being demonstrated at the Cadence booth at Mobile World Congress, being held this week in Barcelona, Spain.
The GSN GNSS receiver running on a Cadence ConnX BBE16 DSP consumes very little power — as low as 10mW of power on a 40nm process — and has the ability to work in lower rates, or snapshots for ultra-low-power mobile scenarios. The solution delivers high-sensitivity tracking, offering a seamless GNSS experience in challenging environments, the companies said.
“GSN’s software-based approach for satellite receivers perfectly complements Cadence DSPs, taking maximum advantage of the flexibility of our DSP architecture,” said Jack Guedj, corporate vice president of Research and Development at Cadence. “The availability of GSN’s software on our ConnX BBE16 further reinforces the strength of our low-power programmable modem strategy for advanced communications.”
“The Tensilica ConnX BBE16 DSP delivers outstanding performance for implementing our GNSS receivers and with a low-power footprint. This provides customers with the ability to easily upgrade their designs to include future satellite systems including Beidou, GLONASS, and Galileo via software,” said Eli Ariel, CEO at GSN. “With no additional silicon costs and at a low cost of deployment, this software-based solution results in a very compelling approach to implement satellite navigation functionality in many products where it otherwise might be impractical.”
