Some embodiments provide a method for a neural network inference circuit that executes a neural network. The method loads a first set of inputs into an input buffer and computes a first dot product between the first set of inputs and a set of weights. The method shifts the first set of inputs in the buffer while loading a second set of inputs into the buffer such that a first subset of the first set of inputs is removed from the buffer, a second subset of the first set of inputs is moved to new locations in the buffer, and a second set of inputs are loaded into locations in the buffer vacated by the shifting. The method computes a second dot product between (i) the second set of inputs and the second subset of the first set of inputs and (ii) the set of weights.
