Abstract: In at least one aspect, a system is configured to use a mapping to determine per-component dynamic power consumed by components in a SoC during execution of instructions, the mapping translating consumed power per one or more instructions into consumed power per component based on a set of determined components (an adjusted set of proposed components) and derived weights, the set of proposed components having been generated to represent the components of the SoC and including a respective proposed component corresponding to each instruction, and the set of proposed components having been adjusted based on the derived weights being produced for the set of proposed components by at least combining two or more proposed components associated with two or more of the derived weights that converged to a shared value, and perform power and temperature management for the SoC in accordance with the determined per-component dynamic power consumption.

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.
