Abstract: The disclosure discloses a method for executing instructions, a device and a computer readable storage medium. The detailed implementation includes: obtaining a first memory access instruction for execution, in which the first memory access instruction includes a first address range of a memory to be accessed; in response to detecting a predetermined instruction for monitoring an accessed address range of the memory, executing the predetermined instruction to obtain a remaining address range not accessed by the first memory access instruction in the first address range; comparing the remaining address range with a second address range included in a second memory access instruction to be executed; and suspending execution of the second memory access instruction in response to the remaining address range at least partially overlapping with the second address range.

Abstract: The present disclosure discloses an instruction prefetching method, a device and a medium. The present disclosure relates to a data storage technology, 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 branch instruction corresponding to the jump instruction is not cached in the target buffer according to a precompiled result, the branch instruction is prefetched from an icache into a candidate buffer corresponding to the processor core to wait for the processor core to fetch the branch instruction from the candidate buffer; the target buffer and the candidate buffer are alternately reused during instruction prefetching.
