Abstract
The present invention relates to a method and a system for performing depthwise separable convolution on an input data in a convolutional neural network. The invention utilizes a heterogeneous architecture with a number of MAC arrays including 1D MAC arrays and 2D MAC arrays with a Winograd conversion logic to perform depthwise separable convolution. The depthwise separable convolution uses less weight parameters and thus less multiplications while it obtains the same computation results as the traditional convolution.
