Abstract
An instruction prefetching method, a device and a medium are provided. The method includes the following: instructions in a target buffer are precompiled before a processor core fetches a required instruction from the target buffer corresponding to the processor core; if it is determined that a jump instruction exists in the target buffer and a jump target instruction corresponding to the jump instruction is not cached in the target buffer according to a precompiled result, the jump target instruction is prefetched from an icache into a candidate buffer corresponding to the processor core to wait for the processor core to fetch the jump target instruction from the candidate buffer; the target buffer and the candidate buffer are alternately reused during instruction prefetching.
