Instruction flagging circuit configured to perform instruction detection and set instruction flags for conditional branch instructions

Abstract

An instruction flagging circuit includes: a first instruction detection sub-circuit for performing instruction detection on to-be-processed instructions to obtain a first detection result, wherein the first detection result includes a first conditional branch instruction and at least one non-jump instruction of the to-be-processed instructions, a jump range of the first conditional branch instruction is within a first range, and the non-jump instruction is to be executed when the first conditional branch instruction does not jump; and a first instruction flagging sub-circuit for setting, according to the first detection result, instruction flags for the first conditional branch instruction and the non-jump instruction to obtain target flagged instructions. The target flagged instructions indicate an instruction execution circuit to execute the non-jump instruction including the instruction flag when it is determined that the first conditional branch instruction jumps.
