US Patent 9916531 Accumulator constrained quantization of convolutional neural networks

An apparatus is described herein. The apparatus comprises an accumulator, a controller, and a convolutional neural network. The accumulator is to accumulate a plurality of values within a predetermined bit width. The controller is to determine a parameter quantization and a data quantization. The convolutional neural network is adapted to the data quantization, wherein a quantization point is selected based on the parameter quantization, data quantization, and accumulator bit width.
