The parallel evaluation of IIR filters – An Implementation

"Algorithms and Parallel Computing" by Fayez Gebali covers the parallelization of IIR filters in chapter 12. This is going to be a field that I need to study for a few days, or weeks before I'm really comfortable discussing results.

I will say that I thank you for submitting this to the discussion on Hacker News. It didn't get a lot of upvotes, but I'm still intrigued by this problem.

I've deleted my earlier post because it does seem to be a difficult question on how to parallelize the "y" portion of IIR filters.

That's definitely an interesting topic. I'll have to give it more of a read and more thought later.
