Measuring the ARM MALI 400 GPU per frame Time

Ravinder

Dear ARM and All,

I am writing a OpenGLES2.0 benchmark application for ARM MALI 400.

the code snippet is like below,

I am seeing the first frame is completing in lesser time than the next frames, and some time the frame time from one frame to another is huge difference.

Why this behavior is observed?

Please help me in measuring the frame time correctly.

------------------------------------------------------------------------------------------------

repeat for 100 frames

Time_elapsed_in_one_Frame =0x00;              

frameTimer.restart();

glDrawElements()

glFinish();

Time_elapsed_in_one_Frame  = frameTimer.elapsed();

------------------------------------------------------------------------------------------------

Thanks,

Ravinder Are
