In addition, when distinguishing the main processor core from other processor cores except the main processor, the distinguishing can be realized based on the ID of the processor core, specifically, a specified ID can be set for the main processor core in advance, so that after the processor core with the specified ID is determined to be the main processor core, the rest processor cores are the other processor cores, and thus, the distinguishing of different processor cores can be realized conveniently and quickly through the method.
