The processor offers functionality for debugging systems with energy management capabilities. This section describes scenarios where the OS takes energy-saving measures when in an idle state.
The different measures that the OS can take to save energy during an idle state are divided into two groups:
The OS takes measures that reduce energy consumption but maintain the processor state.
- Power down
The OS takes measures that reduce energy consumption but do not maintain the processor state. Recovery involves a reset of the core after the power level has been restored, and reinstallation of the processor state.
