Abstract: Aspects of the present disclosure include a method, a device, and a computer-readable medium for restarting an instruction pipeline of a processor that includes a decoupled fetcher. A method comprises detecting, in a processor, a re-fetch event, wherein the processor includes an instruction unit (IU) configured to fetch instructions from a decoupled fetcher (DCF), and simultaneously flushing the IU and the DCF in response to detecting of the re-fetch event.
