Image signal processing on Google's AIY Vision Kit

[kodukulav]

Hi,

A question related to Google's AIY Vision Kit:

I realized that there is already a image signal processor (ISP) on Pi's GPU. However, there is also an ISP on the Myriad2 located on the Vision Bonnet. I wonder which ISP is actually used during workload execution. Is there anyway to check for this?

Thanks,
Venky
