Systems and methods for power management in low power communication device and system

Abstract

A radio module, comprises a battery; and a radio circuit, the radio circuit comprising: a DC-to-DC converter coupled with the batters and configured to convert a battery voltage to a first DC voltage level; at least one regulator coupled with the DC-to-DC converter and configured to covert the first DC voltage level to a second DC voltage level; at least one circuit block coupled with the at least one regulator such that the second DC voltage level is configured to provide power to the at least one circuit block; a real time clock configured to provide a clock signal to the at least one circuit block.

What is claimed: 
     
         1 . A method for dynamically programming a hardware programmable state machine comprising, a plurality of circuit blocks, and a management unit communicatively coupled with the plurality of circuit blocks and configured to implement the hardware programmable state machine defined by a dynamically created, application specific power profile having a plurality of application specific power events, each power event comprising a plurality of transitions between a plurality of power states, each power state defining a different operational state for the plurality of circuit blocks, the method comprising:
 selecting from a plurality of power events only those power events needed to perform the functions required for a specific application, so as to ensure the lowest possible power consumption and longest possible battery life, the selected power events of the plurality of power events constituting the application specific power events and defining the application specific power profile;   generating programming instructions configured to cause the management unit circuit to implement the application specific power profile; and   transmitting programming instructions to the hardware programmable state machine.
