A system includes a high bandwidth memory (HBM) and a convolutional neural network (CNN) engine. The HBM includes a virtual bank portion and a system memory portion. The virtual bank portion is configured to store a feature map data and the system memory portion is configured to support data exchanges with a host. The CNN engine includes a convolutional unit configured to execute convolutional layer instructions, a depthwise convolutional unit configured to execute depthwise layer instructions, and a first on-chip buffer. The first on-chip buffer is configured to receive and store the feature map data from the virtual bank portion or receive and store data results from the convolutional unit. The first on-chip buffer is further configured to send the feature map data or the data results from the convolutional unit to the depthwise convolutional unit for processing.
