Abstract
A hardware accelerator that is efficient at performing computations related to a sparse neural network. The sparse neural network may be associated with a plurality of nodes. One of the nodes includes one or more sparse tensors. The accelerator may compress the sparse tensor to a dense tensor. The sparse tensor may also be structured so that the dense locations in the tensor are blocked or partitioned. The accelerator may transpose the weight tensor and align the partitions of the tensor with the hardware architecture. The structured tensor has a balanced number of active values so that the active values can be processed by an efficient number of operating cycles of the accelerator. The accelerator may also perform bitwise and operation to determine the location of dense pairs in two sparse tensors to reduce the number of computations.
