Abstract
A processing system with multiple processors is switchable between two modes of operation dynamically: symmetrical multi-processing (SMP) and asymmetrical multi-processing (ASMP). The system uses certain criteria to determine when to switch to improve the power consumption or performance. A controller enables control and fast-switching between the two modes. Upon receipt of a switching command to switch between SMP and ASMP, a series or sequence of actions are performed to control voltage supplies and CPU/memory clocks to the multiple processors and cache memory.
