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

A processor, comprising:

• an instruction flagging circuit and an instruction execution circuit, wherein
• the instruction flagging circuit comprises:
• a first instruction detection sub-circuit, configured to perform instruction detection on to-be-processed instructions to obtain a first detection result, wherein the first detection result comprises:
• a conditional branch instruction and at least one non-jump instruction of the to-be-processed instructions, wherein a jump range of the conditional branch instruction is within a first range, and the at least one non-jump instruction is to be executed when the conditional branch instruction does not jump;
• and
• a first instruction flagging sub-circuit, configured to set, according to the first detection result, instruction flags for the conditional branch instruction and the at least one non-jump instruction of the to-be-processed instructions to obtain target flagged instructions, wherein the target flagged instructions are configured to indicate an instruction execution circuit to:
• execute the at least one non-jump instruction comprising the instruction flag in case that it is determined that the conditional branch instruction jumps,
• the instruction flagging circuit is configured to set the instruction flags for the conditional branch instruction and the at least one non-jump instruction of the to-be-processed instructions to obtain the target flagged instructions;
• and
• the instruction execution circuit is configured to execute the target flagged instructions according to a jump situation of the conditional branch instruction and the instruction flags of the target flagged instructions.

An instruction flagging method, comprising:

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