Hi,

Can I use [DPU-PYNQ](https://github.com/Xilinx/DPU-PYNQ) and [Pynq-ComputerVision](https://github.com/Xilinx/PYNQ-ComputerVision) overlays both at the same time?

I mean use resize from Pynq-Computer function while DPU is running?

No. Both designs are separate bitstreams. When you load one, it replaces the other.

You can time share. E.g. Capture an image, load the PYNQ-Computer vision (to PL), run the image through it and save results (back to PS), load the DPU design (to PL- replaces previous overlay), run the results from previous through it.
