sensAI - AI close to the sensors



Easics uses its expertise in system-on-chip design to develop small, low-power and affordable AI engines that run locally, close to your sensors. 

This results in a low and predictable latency and runs with ultra low-power consumption.  Easics’ embedded AI solutions integrate tightly with novel and existing sensors such as image sensors capturing light inside and outside the visible spectrum (such as hyperspectral and thermal infrared), 3D scanning laser (LiDAR), Time-of-Flight (ToF) sensors, radar, microscopy, ultrasound sensors, and microphones.
To create such innovative hardware, easics is developing the next generation of its embedded AI framework. This framework automatically generates hardware implementations of the deep neural networks that make your specific application smart. Easics maps these AI engines on custom ASIC technology and FPGA. The framework and technology offers enough flexibility in terms of different deep learning models and hardware to have a scalable AI engine that is ready is for the future.

sensAI architecture and data flow

The input sensor data and the quantized weights are loaded through a DMA controller into the buffers. Both data and weights are shifted through the convolution engine. The result goes to the accumulator and is finalized in the post processor. The sequencer manages the execution of the subsequent layers of the  network. It generates a continuous flow of output tensors becoming input tensors of the subsequent layers. The final output tensors result is returned to the application microcontroller.

e.g., CNN (ResNet, YOLO, mobilenet, ...), RNN (Deepspeech, ...)

Why choose sensAI: 

  • Low hardware cost: MAC efficiency above 95%
  • Superb flexibility: It supports CNN and RNN on the same core instance. 
  • Fast time to market to embed AI close to the sensor  
  • Customization of the core: in terms of performance, power consumption, area (number of multiplier units) and memory requirements.
  • configure your sensAI core via the easics estimator tool.

Sensors benefit from sensAI:
