Apparatuses, methods, and systems for configurable operand size operations in an operation configurable spatial accelerator

Abstract

Systems, methods, and apparatuses relating to configurable operand size operation circuitry in an operation configurable spatial accelerator are described. In one embodiment, a hardware accelerator includes a plurality of processing elements, a network between the plurality of processing elements to transfer values between the plurality of processing elements, and a first processing element of the plurality of processing elements including a first plurality of input queues having a multiple bit width coupled to the network, at least one first output queue having the multiple bit width coupled to the network, configurable operand size operation circuitry coupled to the first plurality of input queues, and a configuration register within the first processing element to store a configuration value that causes the configurable operand size operation circuitry to switch to a first mode for a first multiple bit width from a plurality of selectable multiple bit widths of the configurable operand size operation circuitry, perform a selected operation on a plurality of first multiple bit width values from the first plurality of input queues in series to create a resultant value, and store the resultant value in the at least one first output queue.
