Abstract
The present invention discloses a method for managing a multi-core processor. The method includes: if a current working mode of the multi-core processor is an asymmetric multiprocessing ASMP mode, a working frequency of at least one other processor than one processor that requests data is less than a first frequency, and a difference between a cache hit ratio value corresponding to the one processor and a cache hit ratio value corresponding to the at least one other processor is greater than or equal to a first threshold, switching the working mode of the multi-core processor to a symmetric multiprocessing SMP mode.
