<p>Embodiments are disclosed for a method of executing instructions in a processing core of a microprocessor. In one embodiment, the method comprises, in a first clock domain, receiving an input from a second clock domain external to the first clock domain, the input comprising an indication from the second clock domain regarding whether to execute an instruction in the first clock domain. The method further comprises synchronizing the input from the second clock domain with the first clock domain, if the instruction is a predicatable instruction and the indication matches a predicate condition that indicates not to perform the instruction, then not performing the instruction, and otherwise performing the instruction.</p> |
