Measuring Power in the K2H EVM

Miguel Aguilar

Hi,

I am trying to see if there anyway in which I can measure power/current etc in the K2H EVM. In particular, regarding the ARM or DSPs.

It is possible by using the UCD devices? Or are there any pins accessible?

Thanks,

Hello Miguel,

The power consumption model for K2H devices are available in below wiki page. I highly recommend you read the entire wiki including the FAQ section before using the power models.

processors.wiki.ti.com/.../Power_Consumption_Summary_for_66AK2Hx_System-on-Chip_(SoC)_Device_Family

You could refer the below thread where the power measurement using UCD device is discussed.

Hi,

One more question. Is there any information about how the power model is actually computed?

Thanks,
Miguel

Hello Miguel,

To my knowledge, We have performed power characterization and identified the power consumption under each scenario. Based on the results we have computed this power consumption model.

Hi,

What I meant is that I would like to see the formulas that use use to compute this estimations.

The spredsheet is locked with a password, therefore it is not possible to appreciate the formation of the model in detail.

It is possible to somehow have access to these formulas that are used in the model?

Thanks,

Miguel

Hello Miguel,

Sorry, i do not have the password to unlock the power consumption model. There is no other document available which gives the formulas used in this model.
