PETALUMA, Calif., July 21, 2019 /PRNewswire-PRWeb/ -- General
Vision's new NeuroShield HDK brings simple and practical AI to the
Xilinx ZYNQ developers' community with a trainable digital neural
network accessible through the ZYNQ7000 ARMĀ®-based processor or
FPGA.
Video, audio, vibration and other sensory inputs can be
acquired, formatted, learned and immediately recognized. Decision
can be taken on-board to control an actuator, transmit or store
data of interest, or else. Typical applications include detection
of abnormal vibrations in an appliance, classification of outdoor
noises from glass debris to bird songs, monitoring of a flame (or
absence of a flame), identification of a person or object in a
field of view, etc.
The NeuroShield board features a digital neural network of 576
neurons, expandable to 4032 neurons. It can learn features
extracted from single or multiple sensors upon the push of a button
or other external or programmatic events managed by the ARM or FPGA
of the ZYNQ SOC. As soon as a learning has occurred, the neurons
can be queried and depending on the application, the ARM or FPGA
can retrieve a simple recognition status (Identified, Uncertain or
Unknown), the category of the closest match or a detailed
classification integrating the response of all firing neurons.
Unlike a conventional CNN or DL approach, the NeuroMem neurons
are capable of intrinsic learning and recognition. Learning does
not require access to massive data bases of annotated models and
the teacher can observe results immediately after teaching a few
relevant examples of each category. Note that the training can also
be done offline since the NeuroShield can be interfaced to a PC via
its USB connector. In either case, the knowledge built by the
neurons can be saved and exchanged between platforms using General
Vision's software tools.
ZYNQ platforms currently tested include the Digilent Arty Z7
(switches & leds, GiGE input, HDMI in and out, audio, 2 PMODs,
Arduino connectors and SD card) and the Avnet MiniZed (switches
& leds, WIFI, BLE, 2 PMODs and Arduino connectors). The General
Vision HDK comes with Vivado and SDK projects and can be edited to
support other ZYNQ7000 development boards.
