Hardware devices and methods for dynamic asymmetrical and symmetrical multi-processor mode switch

Processing system having a plurality of processors may be a multi-processing (symmetrical multi-processing, SMP) and asymmetric symmetric multiprocessing (asymmetrical multi-processing, ASMP) dynamic switching between these two modes of operation. The system uses certain criteria to determine when to switch the power consumption or to improve performance. Controllers between the two modes and fast switching control. After receiving the handover command to handover between SMP and ASMP, executes a series or a series of actions to control the plurality of processors and cache memory supply voltage and CPU / memory clock.
