摘要：【中文】本发明提供一种指令执行方法、处理器和电子设备，其中，指令执行方法包括：根据程序计数器获取待执行的指令；其中，所述程序计数器当前指向第一地址，所述第一地址中存储有第一指令；对所述待执行的指令解码；若确定所述待执行的指令为无效重做指令，则执行所述无效重做指令，并根据所述程序计数器重新获取待执行的指令；其中，所述无效重做指令为指令生成单元生成的且被插入至所述第一指令之前被执行。通过指令生成单元生成无效重做指令，并将无效重做指令插入至第一指令之前被执行，在不改变程序计数器的状态的前提下抵抗了侧信道攻击，提高了抵抗侧信道攻击的效果和效率。 【EN】The invention provides an instruction execution method, a processor and electronic equipment, wherein the instruction execution method comprises the following steps: acquiring an instruction to be executed according to the program counter; the program counter points to a first address currently, and a first instruction is stored in the first address; decoding the instruction to be executed; if the to-be-executed instruction is determined to be an invalid redo instruction, executing the invalid redo instruction, and re-acquiring the to-be-executed instruction according to the program counter; wherein the invalid redo instruction is generated by an instruction generation unit and executed before being inserted into the first instruction. The invalid redo instruction is generated by the instruction generating unit and is inserted into the first instruction to be executed, side channel attack is resisted on the premise that the state of the program counter is not changed, and the effect and the efficiency of resisting the side channel attack are improved.
