Abstract
A disclosed computer-implemented method may include maintaining, within a local memory device (LMD) included in a hardware accelerator (1) a filter matrix corresponding to a filter location included in each of a set of filters of a convolutional layer of an artificial neural network (ANN), and (2) a set of activation vectors corresponding to an active region of an activation volume input into the convolutional layer. The method may also include determining that the active region of the activation volume is contiguous with a padding region associated with at least a portion of the activation volume. The method may further include directing a matrix multiplication unit (MMU) included in the hardware accelerator to execute a matrix multiplication operation (MMO) using the filter matrix and an activation matrix that may include (1) the set of activation vectors, and (2) at least one padding vector corresponding to the padding region.
