Claim One:
1. A circuit for performing neural network computations for a neural network comprising a plurality of layers, the circuit comprising: a systolic array comprising a plurality of cells; a weight fetcher unit configured to, for each of the plurality of neural network layers: send, for the neural network layer, a plurality of weight inputs to cells along a first dimension of the systolic array; and a plurality of weight sequencer units, each weight sequencer unit coupled to a distinct cell along the first dimension of the systolic array, the plurality of weight sequencer units configured to, for each of the plurality of neural network layers: shift, for the neural network layer, the plurality of weight inputs to cells along the second dimension of the systolic array over a plurality of clock cycles, where each weight input is stored inside a respective cell along the second dimension, and where each cell is configured to compute a product of an activation input and a respective weight input using multiplication circuitry.
