I'd agree with that. How clean is the input signal? If you need filtering
too (and I'd bet you do), that takes cycles.

I want to do that on the analog side. That's where I come from, anyway.

Or indeed consider the analogue PI alternative. But as Rickman says, 60kHz
is a fair old whack.

Well, I was talking about 60kHz sampling frequency. Signal bandwidth is
about 25kHz.

Sample rate is what determines how much processing you need to do. You
need to look at whether you can buffer a block of data and process in
one big hunk, or if you have to process each incoming sample. Either
way, you need an idea of what processing you need to do to be able to
say a regular MCU can do it or if you need something faster. Before
you can pick a processor, you need to know your processing requirements
better.
