Feedback Controller - TechTechTechnologies/Prometheus GitHub Wiki
This handles the way feedback is routed from the output of each FSR to the input of each. Right now the idea is that it will take a MODE and route output from LFSRx to the input of LFSR(x+MODE). It also is currently responsible for performing the inversion that each feedback needs.
Apparently we're not allowed to just use VHDL's rol on two signals, so this will have to be implemented elseways. It's basically just N big 1-bit muxes handling N inputs. I don't really know the best way to go about implementing this in VHDL, and I don't really know that it needs to be that general anyway. In any case, I'm gonna leave this open for now.
