Initial 2nd Order IIR Filter implementation, along with quantised C simulation@
Skeletal setup for Notch
WIP for Notch Filter implementation
Untested notch filter
Non-working changes. Fixed some bugs. Gets stuck at 205760
More diagnostic stuff
Fixed missing line; and added more diagnostic indicators. Increased slave address bit width to four, and made the necessary changes in Qsys
Still suck somewhere in the pipeline
Pipeline now completes. Time to check for correct results
Removed all the stuff about flash memory
Minor changes. Requires Testing
Wave samples scaled as a header file for C inclusion
No longer stalls
Testing
Moved FIFO purging around
Basic working structure
Now stalls at reading. Good
Re-added calculation pipeline. Now stalls there, although writefifo has zero items used yet it is stalling?
Adding SD Write pipeline causes the whole thing to stall. Probably due to some quartus' optimisation
Partial implementation of write pipeline. Quartus seems to synthesise some of the stuff away...
