Abstract

See full text

In one example, a hardware accelerator comprises an event register that stores an event; a hardware execution engine; and a controller configured to: extract, from an instruction, parameters of an operation to be performed by the hardware execution engine, and a synchronization primitive of a plurality of synchronization primitives for the event; and based on the synchronization primitive, perform at least one of: controlling a start time of the operation at the hardware execution engine, or determining whether to access the event register. The synchronization primitives include a set operation to set the event and/or a wait operation to suspend the operation at the hardware execution engine until the event is set. The plurality of synchronization primitive defines different conditions to be satisfied in order to perform the set operation.
