Abstract
A voltage scaling system can scale a supply voltage while preventing a processor from communicating with first system components that are rendered unstable from the scaling. On the other hand, the voltage scaling system allows second system components that are stable during the scaling to communicate with the processor. A processor scales a system supply voltage to a target supply voltage. The processor halts operations of the first system components and executes the instruction. When the first system components are halted, the processor cannot access the first system components. The second system components can continue operating during the scaling. A controller that saves power can configure a voltage regulator to scale the system supply voltage to the target supply voltage. Once the target supply voltage is reached, the voltage regulator sends an indication to a power management unit, after which the first system components continue to operate.
