1. Respectively send the decoding result 1, the decoding result 1, the decoding result 2, and the decoding result 2 in the first to the fourth sending periods (as shown in FIG3B);2. Respectively send the decoding result 1, the decoding result 1, the decoding result 1, and the decoding result 2 in the first to the fourth sending periods;3. Respectively send the decoding result 1, the decoding result 2, the decoding result 2, and the decoding result 2 in the first to the fourth sending periods;4. Respectively send the decoding result 1, the decoding result 2, the decoding result 1, and the decoding result 2 in the first to the fourth sending periods;5. Respectively send the decoding result 1, the decoding result 2, the decoding result 2, and the decoding result 1 in the first to the fourth sending periods; and6. Respectively send the decoding result 1, the decoding result 1, the decoding result 2, and the decoding result 1 in the first to the fourth sending periods.  FIG3A is a schematic structural diagram of a processor according to an embodiment of this application. A processor 30 supports X-channel IMT, and X is an integer greater than 1. The processor 30 may include a decoding unit 31 and a processing unit (Processing unit, PU) 32. When 1 ≤ Z < X, the quantity of threads actually executed by the processor 30 is less than the maximum quantity of threads supported by the processor 30. The instruction decoder 311 schedules instructions according to the instruction scheduling sequence described in the foregoing embodiment of FIG3A. The following describes two possible instruction scheduling sequences of the instruction decoder 311.
