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.

    The exact power consumption depends on large number of factors:

    • Cell libraries
    • Synthesis tools
    • Timing constraints
    • Synthesis options (e.g. clock skew, fan out limit)
    • Other implementation options (floor plan, scan insertion, etc)
    • Processor's configuration options (e.g. how many IRQ to support, do you need MPU? etc)
    • Exact signal toggling activities (Note: even running the same program code with different data can get different results).
    • Environmental factors (temperature, voltage, phase of the moon... just kidding )

    If you need to get more information, please contact local ARM sales team, they can provide some more data. (But it won't cover all the possible cases).

    Hope this helps.

    regards,
