System and method of monitoring a central processing unit in real time

摘要

Devices and methods for monitoring one or more central processing units in real time are disclosed. The method may include monitoring state data associated with the one or more CPUs in real-time, filtering the state data, and at least partially based on filtered state data, selectively altering one or more system settings. A device may include means for monitoring state data associated with the one or more CPUs in real-time, means for filtering the state data, and means for selectively altering one or more system settings at least partially based on filtered state data. A device may also include a sub-sampling circuit configured to receive a hardware core signal from the central processing unit and output a central processing unit state indication, and an infinite impulse response filter connected to the sub-sampling circuit and configured to receive the central processing unit state indication from the sub-sampling circuit.

1. A method of monitoring a central processing unit in real time, the method comprising:
receiving a hardware core signal from the central processing unit at a sub-sampling system; determining a state of the central processing unit based at least in part on the received hardware core signal; generating sub-sampling data based at least in part on the determined state of the central processing unit; sending the sub-sampling data to an infinite impulse response filter; selecting an alpha coefficient based on a value of the sub-sampling data; filtering the sub-sampling data in the infinite impulse response filter using the selected alpha coefficient to generate filtered data; comparing the filtered data to a threshold value in the infinite impulse response filter; and adjusting a voltage or frequency of the central processing unit based on the comparison.
