[C6727] Power Measurement

Hi,

I have a C code working on PADK C6727 and CCS v3.1. I want to measure the power consumption by the whole code and some of its  segments. How can I do this? Is there any way I can do this by CCS.

Thanks,

Abhishek Seth.

    I think that we may not have a terrific solution for figuring this out. CCS is a code debugger and, to my knowledge, has no capability to measure any form of power consumption the DSP or its surrounding components. I have seen some methods of power measurement whereas the power consumed is measured at the supply itself.

    I will look around and see if anyone has any good measurement methods to share.

    The only way to measure power consumption will be to put a current-sensing tool between the power supply and the device. It is common for the 1.2/1.4V supply to only drive the C6727, but the 3.3V supply will often go to many devices, meaning you have to find a way to isolate the DSP for the I/O power measurement.

    And you will void your warranty (if any) on the PADK when you start lifting pins to make these measurements.
