Abstract: A digital integrated circuit comprising may include a digital sensor circuit that converts binary bit patterns of wires in a sub-circuit over a given time into a single integer value that represents the total activity of a sub-circuit, and a digital data processing circuit that receives multiple activity integer values from multiple digital sensors in multiple sub-circuits and logically combines the values or uses a lookup table to output a single integer value that represents the total activity of a larger sub-circuit.

Abstract: A power generation system includes a plurality of energy conversion devices for generating a plurality of power signals based on one or more sensed environmental conditions. The system further includes a plurality of power conditioning circuits each coupled to one or more of the energy conversion devices for receiving the power signals and storing energy in an energy storage system. The system also includes a selection circuit coupled to at least one of the power conditioning circuits and receiving a first input power signal from one of the power conditioning circuits and a second input power signal. The selection circuit is configured to deliver an output power signal representing a selection from between the first and second input power signals based on a relative voltage level of the first and second input power signals. A method of power generation, and associated power module, are also disclosed.

Abstract: Power consumed by a digital circuit that contains multiple sub-circuits may be computed. Each sub-circuit may include more than one transistor and have at least one input. A signal transition sensor may be connected to an input to each sub-circuit and configured to count the number of signal transitions at the input or to time the duration of a signal transition at the input. Weight information may be stored that is indicative of an amount of power that is being consumed by each sub-circuit based on a count that is counted by or a time duration that is timed by each signal transition sensor that is connected to an input of that sub-circuit. The amount of power being consumed by the digital circuit may be computed based on a count that is counted by or a time duration that is timed by each signal transition sensor and the weight information.

Abstract: A digital integrated circuit may include a digital data processing circuit having multiple signal lines that each go through signal transitions during operation of the digital data processing circuit. A digital counter circuit may count the combined number of signal transitions that take place on at least two of the multiple signal lines during operation of the digital circuit. A digital counter circuit may count the number of times a particular pattern of signal transitions takes place on at least one signal line during operation of the circuit. A computer program may receive information indicative of a composition of a digital integrated circuit, input vectors to the digital integrated circuit, and how much power is being consumed by the digital integrated circuit under each of the input vectors. The program may output information indicative of an amount of power being consumed by each of multiple, different sub-sections of the digital integrated circuit while responding to the input vectors.
