Is there a way for me to estimate power usage for various ARM cores (Cortex-M0,1,3,4 )?

Karthik Ganesan

Hi, I'm new to development with ARM and I was wondering if there is a way to estimate power usage for the different ARM cores (such as ARM Cortex-M0, -M1, -M3, -M4)? I'm thinking of maybe a program that can accept code compiled for these cores and can estimate how much power they would use if they were to run on actual silicon.

    Hi Allen,

          Thank you for your response. I understand how challenging it would be to provide such data. I was hoping to maybe get normalized data i.e for a given node, compared to one core the other cores consume either 0.x times or 1.x times the power.

          I was able to find the uA/Mhz data from ARM for the cores when running. how accurate would it be for me to use that as a baseline to estimate power usage. if i needed my core to run at 100 Mhz, would it be atleast a first order approximation to estimate the active power using this number?

    thank you,
