Abstract
Task execution among a plurality of processors that are configured to operate concurrently at a same global Voltage/Frequency (VF) level is controlled by using a global power manager to control VF switching from one VF level to another VF level, the same current VF level governing VF settings of each processor. Each of the processors controls whether it will wait for a VF switch from a current VF level to a next VF level prior to enabling execution of a next scheduled task for the one of the processors, with the decision being based on whether a current VF level is higher than the next scheduled VF level. The global power manager performs VF level switching at least based on a timing schedule, and in some but not all embodiments, also on whether all processors indicate that they are waiting for a VF level switch.
