Abstract
A computer processing device transitions among a plurality of power management states and at least one power management sub-state. From a first state, it is determined whether an entry condition for a third state is satisfied. If the entry condition for the third state is satisfied, the third state is entered. If the entry condition for the third state is not satisfied, it is determined whether an entry condition for the first sub-state is satisfied. If the entry condition for the first sub-state is determined to be satisfied, the first sub-state is entered, a first sub-state residency timer is started, and after expiry of the first sub-state residency timer, the first sub-state is exited, the first state is re-entered, and it is re-determined whether the entry condition for the third state is satisfied.
