1. A method for controlling operations of a Central Processing Unit, CPU, associated with a nominal clock frequency, the CPU being coupled to an input/output, I/O, range and configured to deliver input to an application, the method comprising controlling the CPU to poll the I/O range for input to the application, wherein the polling is repeated until a poll results in input to the application, the method characterized by:
monitoring whether or not each poll results in input to the application; and adjusting a clock frequency at which the CPU operates, to a predetermined first clock frequency lower than the nominal clock frequency, if a pre-defined number of polls resulting in no input is detected. |
