TX1 GPU utilisation for Camera HDR processing

we are working on a prototype using TX1.

We are using a pre integrated/supported OV camera sensor with 1080p resolution & 30fps which give raw HDR output, and If we depend on TX1 onboard HDR processing software, what would be the GPU % utilisation for this? (we do not want to use the extra HDR ISP hardware with camera sensor)

Hi Tejagudena,

You could try running ~/tegrastats and look for GR3D:

sudo ~/tegrastats
[sudo] password for ubuntu:
RAM 277/3854MB (lfb 700x4MB) SWAP 0/0MB (cached 0MB) cpu [0%,0%,0%,0%]@1912 EMC 0%@1600 AVP 5%@115 VDE 0 GR3D 0%@76 EDP limit 1912
RAM 277/3854MB (lfb 700x4MB) SWAP 0/0MB (cached 0MB) cpu [1%,0%,0%,1%]@102 EMC 1%@408 AVP 33%@12 VDE 0 GR3D 0%@76 EDP limit 1912

EMC – external memory controller, bus%@MHz
AVP – audio/video processor, processor%@MHz
VDE – video decoder engine, %MHz
GR3D – GPU, processor%@MHz
