An integrated circuit (e.g., a system application processor IC) includes power supply lines that include a section having a known resistance. Measurement connections across the section are also present. The measurement connections may run to an Analog to Digital Converter (ADC). The ADC measures the voltage drop across the section and therefore the power consumed by the circuitry supplied by the power supply line. The power consumption by any particular circuitry in the IC may be monitored, from entire processing cores, down to single transistors. An analysis system may read the power consumption measurements and accordingly adapt the operation of the code segments in the system to meet specified power or energy consumption targets, e.g., to minimize the power and energy consumption. |
