In the TK1 board, I am running an algorithm whose computational load (i.e. amount of work the algorithm does) depends on the data it receives at an input. For e.g., suppose the algorithm is receiving light intensity from a sensor. If the light intensity does not change, the algorithm will not compute anything. That is, its computational load is minimum.
If the light intensity changes, the algorithm will compute a n-point FFT of the light signal where the value of n depends on the change (more change will require larger n). That is, the computational load of the algorithm varies with the data.
We want to find out the computational load of the algorithm by measuring some quantity (e.g. voltage, current) in the TK1 board. What is this quantity? We want this quantity to be:
Sensitive (i.e. the quantity should change as soon as the computational load changes), and
Specific (i.e. the quantity should change enough for the change to be clearly detectable when measured and it should not change due to reasons other than computational load).
Thanks in advance!
