Board for power measurement and optimization work

kamesh419
kamesh419 over 8 years ago

hello,

 

I would like to measure current and voltage of CPU, GPU and Memory individually. I have access to high end national instruments measuring modules. I am expecting to put my probes at the output of the regulator which supplies current and voltage to CPU, GPU and Memory. The voltage drop across the NI modules is very very low (input impedance is 12mOhms for NI modules). So, it will not impact the performance of the processor. I am not expecting ready made measurement points for the same. We have good knowledge of soldering boards in house. Money is also not a problem. So, I am expecting to have good schematics from which I can know where exactly I need to put my probes on. Also, good operating system support for us to run benchmarks and utilities like cpufreq, cpuidle etc is mandatory. We would like to optimize our algorithms and benchmarks for energy and temperature.

 

We recently bought Nvidia Jetson TX1. But the schematics for the daughter board are not available. Also, the Thermal Transfer Plate (TTP) is applied in a special process which once taken apart cannot be put back together without specialized equipment.

 

Can you recommend any board with available schematics, decent enough processor to run benchmarks and easy enough to do power measurements like I described?

 

Thank you very much.
