DaDianNao: A Neural Network Supercomputer

A custom multi-chip machine-learning architecture containing a combination of custom storage and computational units, with electrical and optical inter-chip interconnects separately is introduced, and it is shown that, on a subset of the largest known neural network layers, it is possible to achieve a speedup of 656.63× over a GPU, and reduce the energy by 184.05× on average for a 64-chip system.
