Abstract

Some embodiments provide a neural network inference circuit (NNIC) for executing a neural network that includes multiple computation nodes at multiple layers. The NNIC includes multiple core circuits including memories for storing input values for the computation nodes. The NNIC includes a set of post-processing circuits for computing output values of the computation nodes. The output values for a first layer are for storage in the core circuits as input values for a second layer. The NNIC includes an output bus that connects the post-processing circuits to the core circuits. The output bus is for (i) receiving a set of output values from the post-processing circuits, (ii) transporting the output values of the set to the core circuits based on configuration data specifying a core circuit at which each of the output values is to be stored, and (iii) aligning the output values for storage in the core circuits.
