Abstract
A special-purpose, hardware-based accelerator may include an input subsystem configured to receive first and second vectors as operands of a full dot-product operation. The accelerator may also include a sparsity-aware dot-product engine communicatively coupled to the input subsystem and configured to perform adaptive dot-product processing by: (1) identifying, within the first and second vectors, at least one zero-value element and (2) executing, in response to identifying the zero-value element, a reduced dot-product operation that excludes, relative to the full dot-product operation, at least one mathematical operation in which the zero-value element is an operand. The accelerator may also include an output subsystem that is communicatively coupled to the sparsity-aware dot-product engine and configured to send a result of the reduced dot-product operation to a storage subsystem. Various other accelerators, computing systems, and methods are also disclosed.
