Abstract: An electronic system may include: a camera to capture a current image; an image processor to generate current image data items; and a splitter circuit to generate first and second images having respective first and second image data items. The splitter circuit splits each current image data item into a first image data item with a first set of bits and a second image data item with a second set of bits distinct from the first set of bits. The first and second image data items correspond to two distinct precisions less than a precision of the current image data items. The electronic system may also include distinct binary neural network circuits to independently process the first and second images to generate first and second processed image data items; and a merger circuit to combine the processed image data items to recover output image data items for display.
