Evaluation of input data rarity in calculation units of a neural network

摘要

One or more machine-readable storage devices storing instructions executable by the one or more processing devices to perform operations comprising: receiving, by a computing device, a plurality of input activations, wherein the input activations are provided at least in part from a source external to the computing device is; Determining, by a controller of the computing device, whether each of the plurality of input activations has one of a zero value or a non-zero value; Storing at least one of the input activations in a memory bank of the computing device; Generating, by the controller, an index comprising one or more memory address locations having input enable values that are non-zero values; and providing, by the controller and the memory bank, at least one input enable on a data bus accessible by one or more units of a computation array, the activations being provided at least in part from a memory address location associated with the index.
