DaDianNao:机器学习超级计算机 – MICRO2014

Abstract ：

We show that, on a subset of the largest known neural network layers, it
is possible to achieve a speedup of 450.65x over a GPU, and
reduce the energy by 150.31x on average for a 64-chip system.

III. THE GPU OPTION

1）their (area) cost is high because of both the number of hardware operators and the need to remain reasonably general-purpose.
2) Second, the total execution time remains large (up to 18.03
seconds for the largest layer CLASS1)
3) Third, the GPU energy efficiency is moderate.
