Abstract
Some embodiments provide a neural network inference circuit (NNIC) for executing a neural network. The NNIC includes a first circuit that outputs dot products for computation nodes of a first set of neural network layers, that include dot product computations of sets of weight values with sets of input values. The NNIC also includes a second circuit that outputs values for computation nodes of a second set of neural network layers, that apply a set of calculations that do not include dot products to sets of input values. The NNIC also includes a selection circuit that selects a dot product output from the first circuit when a current layer being processed by the NNIC belongs to the first set of layers, and selects a non-dot product output from the second circuit when the current layer belongs to the second set of layers.
