Trust. Privacy. Confidentiality. These are three important concerns for designers of IoT edge devices. Today NXP announced that they are addressing these concerns with two new platforms that feature secure execution environment (SEE) to give developers access to “unprecedented” security capabilities.

These platforms provide a multi-layered, hardware-enabled protection scheme to secure IoT edge devices and cloud-to-edge connections. This security, more and more, requires voice activation and recognition. The Cadence Tensilica HiFi 4 DSP “enables efficient local audio pre-processing, immersive 3D audio playback and voice-enables experience.” Our HiFi 4 DSP enhances the NXP platforms’ machine learning (ML) experience with 4x 32-bit MACs, vector FPU, 256-bit wide access bus, and DSP extensions for special activation functions.

Yes, machine learning is being designed in everywhere these days. No longer can edge devices just gather data and send it to the cloud. Edge devices need to be smart, and do a lot of the processing on the spot. After all, not all edge applications are Wi-Fi enabled or can rely on consistent communications.
