1. A method comprising:

  • storing a representation of a thermal model at one or more points of a data processing system in a memory, the thermal model using a filtering algorithm to filter temperature data from at least one temperature sensor at a plurality of frequencies to compensate for time-based under estimation and over estimation in the thermal model, the thermal model having a steady state portion and a transient temperature portion estimated separately from each other;

    applying power to the data processing system;

    receiving the temperature data from the at least one temperature sensor in response to the applied power; and

    estimating an instantaneous temperature at the one or more points based on the temperature data by combining the steady state portion and the transient temperature portion of the thermal model.
