Hi!
Is it possible to speed up IIR filter with CUDA? As IIR filter is defined recursively it’s quite challenging.

This is outside my area of expertise. Have you performed a literature search? A simple search of the literature appears to indicate that parallelized GPU implementations of IIR filters are possible, for certain specific use cases and/or subject to specific constraints.
I used the following search terms with Google Scholar: GPU IIR filter

Hello,
maybe our old paper could help you:
