Measure memory bandwidth to GPU

yuansong — Mon, 18 Nov 2013 10:30:10 GMT

I'm trying to figure out a good way to measure memory bandwidth to GPU when I run OpenGL ES applications (with shaders) on my i.MX6 DL board. I could estimate it by calculating pixels and fps. But I wonder how much data is precisely copied to the Vivante GPU and back as it executes shaders.

It would be great if anyone can share your idea about how this can be done :-)

I believe we already have a tool from vivante that can provide you this information, I will check if it is already available and let you know.

andre

I was investigating your question and I ended up that your suggestion is the best one, we do have a tool from vivante, but it is for internal use only and can´t be released to anybody outside FSL.
