Amza Visual Sense and Alif Semiconductor have demonstrated an optimized face detection model running on Alif’s Ensemble microcontroller based on Arm IP. They both deal with their confidence as they choose to embark on their play activities.

The emergence of optimized silicon, models and AI and machine learning (ML) frameworks has made it possible to perform advanced AI prediction functions such as eye tracking and edge facial recognition, low power and low cost operation. This opens up new cases of use in areas such as industrial IoT and consumer applications.

Making edge devices Intensity faster

Using Alif’s Ensemble Multipoint Control Unit (MCU), which Alif claims to be the first MCU using the Arm Ethos-U55 microNPU, the AI ​​model executes “order of magnitude” faster than the CPU-only solution with the M55. 400MHz Alif seems to mean two orders of magnitude, as the footnotes state that the high-performance U55 took 4ms compared to 394ms for the M55. The high efficiency U55 executed the model in 11ms. The Ethos-U55 is part of Arma’s Corstone-310 subsystem, for which it launched new solutions in April.

Emza said it has trained a fully “civilized” face detection model at NPU that can be used for facial examination, facial angle estimation and facial landmarks. The Arm’s open-source AI repository includes a full application code called the “ML Embedded Evil Kit”, making it the first Arm AI ecosystem partner to do so. The repository can be used to measure runtime, CPU demand, and memory allocation before silicon becomes available.

“To unleash the potential of Endpoint AI, we need to make it easier for IoT developers to access high performance, less complex development flows and optimized ML models,” said Mohamed Awad, Vice President and Arm Embedded at IoT. “Alif’s MCU is helping to redefine what is possible at the smallest endpoints, and Emza’s contribution of optimized models to the Arm AI open-source repository will accelerate the same AI development.”

Amza claims that its visual sensing technology is already shipping to millions of products and with this demonstration, it is expanding its optimized algorithms to SoC vendors and OEMs.

“As we look at the dramatically expanding horizons for TinyML Edge devices, AMZA is focused on enabling new applications across a wide range of markets,” said Yoram Zilberberg, CEO of AMZA. “There is virtually no limit to the use of visual sensing that can be supported by new powerful, highly efficient hardware.”
