Abstract
A system and method for multiplying matrices, and method for training a convolutional neural network (CNN), are provided. The system includes a processor and a matrix multiply accelerator (MMA). The processor is configured to generate, based on an input tensor, a number of basic block matrices, each basic block matrix including a number of elements; for each basic block matrix: prune, based on a sparsity value, the elements of the basic block matrix, generate a mask for the basic block matrix, each mask including a number of bits, each bit corresponding to a different element of the basic block matrix, and compress the basic block matrix to generate a compressed basic block matrix having fewer elements than the basic block matrix. The MMA is configured to multiply, based on the masks, the compressed basic block matrices and a weight matrix to generate an output matrix.
