Simple FIR filter using VHDL

[Altera_Forum]

help me to Design and implementation of Simple Finite impulse Response filter using VHDL with some explanation algorithm.

I suggest to read the principles of FIR first of all. After that decide floating point or fixed point implementation. Than you can write a state machine for it with multiplication, summing and shifting. Altera provides core for FIR design with GUI interface and manual. I only use my own code for IIR code with small number of floating point coeffs, for other applications fir compiler is much more useful.

The slides and the code have explanations.  Cheers, Dave
