Devices and methods for power allocation

A method for allocating power among a plurality of circuits in a communication device, the method comprising:

• determining a power budget for allocating to the plurality of circuits from a power supply information;
• receiving an activity status from a first circuit of the plurality of circuits;
• determining a first power value based on the activity status;
• deriving a second power value based on the first power value and the power budget;
• and
• allocating power to one or more remaining circuits of the plurality of circuits based on the second power value.

One or more non-transitory computer-readable media storing instructions thereon that, when executed by at least one processor of a communication device, direct the at least one processor to perform a method comprising:

• determining a power budget for allocating to a plurality of circuits from a power supply information;
• receiving an activity status from a first circuit of the plurality of circuits;
• determining a first power value based on the activity status;
• deriving a second power value based on the first power value and the power budget;
• and
• allocating power to one or more remaining circuits of the plurality of circuits based on the second power value.

A communication device comprising a battery discharge controller for controlling a plurality of processing blocks, the battery discharge controller configured to:

• derive a function of a remaining data processing capacity dependent on battery current;
• select a range of battery current from the function delivering a desired data processing capacity;
• and
• configure one or more of a plurality of processing blocks of the plurality of processing blocks based the selected range.
