Partnership to develop low-power geolocation IP
Nestwave is to use the ARC EM9D processor IP from Synopsys for a low power geolocation design for IoT modems

Nestwave is to combine its soft core geolocation IP with the Synopsys DesignWare ARC IoT Communications IP Subsystem for a complete low-power global navigation satellite systems (GNSS) IP for integration into IoT modems.

The collaboration will provide designers with a power-efficient, high-accuracy GPS for battery-operated devices without the additional cost of a dedicated GNSS chip. Nestwave's split device and cloud architecture reduces power consumption by up to 10 times that of geolocation systems currently on the market, extending the life of battery-operated IoT devices.

"Today's advanced navigation systems are facing unique challenges when being implemented in power-constrained IoT devices," said Ambroise Popper, CEO at Nestwave. "By combining Nestwave's low power geolocation software with Synopsys' efficient ARC IoT Communications IP Subsystem, we can deliver a geolocation solution that offers greater accuracy, lower power consumption, and lower cost compared to existing GNSS solutions."

The ARC IoT Communications IP Subsystem is an integrated hardware and software product that combines the Synopsys DSP-enhanced ARC EM9D processor, hardware accelerators, dedicated peripherals, and RF interface to deliver efficient DSP performance for ultra-low bandwidth IoT applications. Nestwave's GNSS IP takes advantage of the ARC EM9D processor's efficient DSP capabilities and ability to add dedicated hardware accelerators or custom instructions using APEX technology to reduce frequency requirements, giving customers additional performance bandwidth. In other words, the ARC EM9D processor and custom instruction extensions provide performance boosts for Nestwave's algorithms while minimizing processor frequency requirements. The ARC EM9D processor is supported by the MetaWare Toolkit, which includes a rich library of DSP functions, allowing software engineers to rapidly implement algorithms from standard DSP building blocks.
