Infering the GPU Active cycles in Mali T-628

maasa

Hi ,

I have the following questions regarding Mali T-628 GPU.

 I am running a 3D convolution OpenCL kernel in Mali T-628 GPU (set of 4 cores device).  I obtain the GPU cycles counter using Streamline

The GPU Vertex-Tiling-Compute:Activity counter shows 100% utilization . So this translates to 100% GPU utilization.

Then the GPU active cycles should match the runtime right?

In a sampling interval of 1s , the GPU active cycles should be 600*10^6 whereas the GPU active cycles reported by streamline is 3141810

Why this discrepancy?

Please help me understand this.

Thanks
