Decoding method, processor, chip and electronic equipment

The embodiment of the invention provides a decoding method, a processor, a chip and electronic equipment, and the method comprises the steps: generating an instruction fetching request carrying at least one switching mark, and enabling the switching mark to at least indicate an instruction position for the switching of a decoder group; in response to the micro instruction obtained by decoding of the decoder group, acquiring an instruction stream fetched by the instruction fetch request, and determining an instruction position for switching the decoder group according to a switching mark carried by the instruction fetch request; according to the instruction position, the instruction stream is distributed to a plurality of decoder groups for parallel decoding, a switching mark is attached to a target microinstruction obtained by decoding a target instruction, and the target instruction is an instruction corresponding to the instruction position; and responding to the microinstruction obtained by searching the m
