How to parallelize IIR filter with CUDA?


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
