Abstract
An augmented reality device having a pair of glasses and an artificial neural network partially implemented via a passive neural network and partially implemented via digital circuits. The passive neural network can process image lights representative of a scene in a view of the pair of glasses to generate a light pattern. An array of light sensing pixels can convert the light pattern into data representative of outputs of a first set of artificial neurons of the artificial neural network. A processor can execute instructions to perform computations of a second set of artificial neurons of the artificial neural network responsive to the outputs of the first set of artificial neurons. A digital accelerator can accelerate multiplication and accumulation operations applied on weight matrices of the second set of artificial neurons.
