    Synaptics' Katana-based edge artificial-intelligence (AI), low-power SoC is powerful enough to analyze a video stream with machine-learning (ML) models that can visually detect actions like falling. Ananda Roy highlights this feature in the video. 

    The demonstration was done using Synaptics evaluation kit (Fig. 1). The platform, based on the Katana SoC, adds audio input via two microphones and a Himax QVGA video module along with an ambient-light sensor and accelerometer. The Wi-Fi/Bluetooth module provides wireless connectivity. There's even an OLED display for immediate user feedback.

    Katana is a multicore SoC with a dual DSP to handle ML models in real-time (Fig. 2). It also manages audio and video data. A Cortex-M3 core provides system-management support.

    I earned a Bachelor of Electrical Engineering at the Georgia Institute of Technology and a Masters in Computer Science from Rutgers University. I still do a bit of programming using everything from C and C++ to Rust and Ada/SPARK. I do a bit of PHP programming for Drupal websites. I have posted a few Drupal modules.  

    I still get a hand on software and electronic hardware. Some of this can be found on our Kit Close-Up video series. You can also see me on many of our TechXchange Talk videos. I am interested in a range of projects from robotics to artificial intelligence.
