The invention discloses a management method of a multi-core processor. The method comprises the followings: if a working mode of the current multi-core processor is an asymmetric multi-processing ASMP mode, working frequency of at least one other processor is less than first frequency apart from one processor in charge of data requests and the cache hit percentage value of one processor corresponding to at least one other processor is more than or equal to a first threshold value; the working mode of a multi-core processor is switched to a symmetric multi-processing SMP mode; if the working mode of the current multi-core processor is a SMP mode, the cache hit percentage value of one processor corresponding to one processor is more than or equal to a second threshold value;all processors of the multi-core processor have uneven usage rates; the usage rate of N processors of the multi-core processor is larger than the first usage threshold valve and the working mode of the multi-core processor is switched to be an ASMP mode; and the N is more than or equal to 1 and less than or equal to the number of the processors of the multi-core processor minus one.
