Nordic Semiconductor is ready to purchase U.S. startup Atlazo, primarily for the corporateās AI {hardware} IP and experience. The IoT SoC maker based mostly in Oslo, Norway, plans so as to add in-house {hardware} AI acceleration IP to units throughout its portfolio, Kjetil Holstad, govt VP of technique and product administration, informed EE Instances.
āWhereas Nordic prospects at this time are utilizing [standalone AI accelerators] alongside Nordic SoCs, Atlazo represented an opportunity to pay money for know-how that we will begin to embed in our units,ā he mentioned.
The acquisition nonetheless wants regulatory approval. But when all goes effectively, Atlazo IP might start showing in Nordic merchandise in as few as 12-18 months, Holstad mentioned.
Nordicās product vary consists of wi-fi microcontrollers (MCUs) with ultra-low energy Bluetooth, ANT, Thread and ZigBee connectivity for purposes like wearable medical and health units, however the firm has additionally expanded into mobile and WiFi chips lately.
āI donāt see a limitation on the place [Atlazoās AI accelerator] know-how can match,ā Holstad mentioned. āIt may not be the identical implementation in all merchandise, however I do suppose it belongs throughout our applied sciences and throughout what Nordic does. If we’re desirous about IoT, this know-how is coming, full steam forward.ā
Atlazo, based in 2016 in San Diego, Calif., has eight staff members who will be part of Nordic.
Nordic final yr introduced the acquisition of modern static SRAM startup Cell Semiconductor, whose low-power, low-leakage reminiscence IP was already in all Nordicās wi-fi IoT SoCs. Nordic additionally beforehand acquired Creativeness Applied sciencesā WiFi IP and staff in 2021.

āAnybody can go to TSMC and use their reminiscences, however then everybody who’s doing that performs the identical,ā Holstad mentioned. āRecollections, acceleration and connectivityāall of those are essential for getting the ultra-low energy facets proper. For us, itās about determining how we may be higher than everybody else and thatās how each [Mobile and Atlazo] acquisitions got here in.ā
Atlazoās first-generation {hardware} IP for AI acceleration, Axon 1, can speed up many forms of neural community, together with these used for the medical and wellness sensor sorts, that are vital to Nordicās buyer base. Axon 1 may also deal with neural networks for imaginative and prescient, voice and vibration sensing, together with LSTM (lengthy brief time period reminiscence) and GRNN (basic regression neural networks), in addition to characteristic extraction methods like MFCC (mel-frequency cepstral coefficients).
Axon 1 is silicon-proven within the startupās AZ-N1 SoC, which launched in 2021. Nordic won’t proceed to promote the AZ-N1, however will combine next-generation Axon IPāalready beneath growthāinto its merchandise.
From Nordicās perspective, itās vital to have this IP in-house to drive its growth, Holstad mentioned.
āWhatās core for Nordic is the ultra-low-power facet, thatās the place we attempt and the place we differentiate, but additionally on the convenience of use,ā he mentioned. āWe might have licensed from or collaborated with others, however we predict that is going to be important to prospects and we wish to personal that know-how so we will actually nail the ultra-low energy facets of it.ā
Holstad added that Nordicās prospects are fixing extra and greater issues with Nordic chips than ever earlier than.
āWe went by a journey of turning into an IoT firm, at the start,ā he mentioned. āNow weāre beginning to have a look at increasing inside IoT and inside ultra-low energy, extending the footprint of issues we will remedy on behalf of our prospectsā¦. Weāre now doing multi-core units which have lots of computational energy, extra like an MCU with radio than a radio with an MCU.ā
With the sector of tinyML gaining traction throughout the trade, AI algorithms have gotten small and light-weight sufficient to run on general-purpose Arm MCU cores. Present Nordic buyer purposes for tinyML sometimes embody anomaly-detection and sound-detection purposes.
Nordicās current AI software program stack is predicated on Armās ML libraries, and the corporate companions with third events, together with Edge Impulse, for the very best developer expertise, Holstad mentioned.
The Atlazo buy comes with some sensor-specific neural community algorithms, which can be supplied as Nordicās in-house fashions sooner or later.
General, nevertheless, the corporate additionally desires to permit its prospects to distinguish, relying on their stage of expertise and assets, he added.
āIf IoT goes the place we predict itās going, it wants extra [AI compute],ā he mentioned. āYou can’t simply have a stream of all of the sensor information on this planet as much as the cloud and let AWS remedy issues; thatās not sustainable, for thus many causes. Our prospects want to unravel issues as near the sensor as potential, and we now see a must transcend utilizing traditional general-purpose Arm [compute] to unravel that downside.ā
Including {hardware} acceleration for IP additionally is smart for purposes that match into the Arm core at this time, Holstad mentioned.
āIf an inference takes 100 milliseconds on an Arm core, it would take [a fraction of that] on an accelerator, so that youāll save lots of energy,ā he mentioned. āSo if the cost-value proposition is true, will probably be included [across all Nordic product lines]. Thereās all the time the exception to the rule, however proper now I believe we will make a very good worth proposition for together with [AI acceleration] in just about all the pieces we’re desirous about doing sooner or later.ā
Atlazo additionally has sensor interface and energy administration IP alongside basic experience in ultra-low energy design, which might be added to Nordicās toolbox for āfixing the worldās battery issues,ā Holstad mentioned.
If regulators approve the acquisition, Atlazoās San Diego, Calif., workplace would grow to be Nordicās third U.S. outpost, along with the Cell Semiconductor workplace in Seattle and Nordicās current base in Portland, Oregon.
