摘要： A method for automatically scaling estimates of digital power consumed by a portion of an integrated circuit (IC) device by the operating frequency of the portion of the IC are described herein. The method may include obtaining an energy value which may correspond to an amount of energy used by the portion of the IC. A cumulative energy value may be generated by repeatedly, at a frequency proportional to the operating frequency of the portion of the IC, obtaining energy values and adding each obtained energy value to a sum of energy values for the portion of the IC. The cumulative energy value may be sampled at a time sample interval to generate an estimate of the portion of the IC's digital power consumption that is automatically scaled with the operating frequency of the portion of the IC.

摘要： A method and system for varying sampling frequency to avoid software harmonics when sampling digital power indicators are described herein. A power monitor may repetitively sample, at a variable sampling rate based on a variable delay time, multiple signals of an IC device to obtain energy values. The variable delay time may be based on a pseudo-random value or a predictable value. The variable delay time may indicate a number of delay cycles that may be inserted between the repetitive samples of the energy values. The variable number of delay cycles between energy value samples may produce a variable sampling rate. A variable sampling rate may avoid alignment with software harmonics which can cause an inaccurate representation of power consumption. The multiple samples obtained by repetitively sampling energy value for the portion of the IC may be summed to generate a cumulative energy value for the portion of the IC.
