Abstract
A core of neural processing units is configured to efficiently process a depthwise convolution by maximizing spatial feature-map locality using adder trees. Data paths of activations and weights are inverted, and 2-to-1 multiplexers are every 2/9 multipliers along a row of multipliers. During a depthwise convolution operation, the core is operated using a RS×HW dataflow to maximize the locality of feature maps. For a normal convolution operation, the data paths of activations and weights may be configured for a normal convolution configuration and in which multiplexers are idle.
