Re: IIR filter example ?

Mike,

What's the advantage of the coding style you demonstrated in this example
with procedures instead of direct assignments in the process?

Thanks,

Since the template is always the same,
I can write synth code quickly and it
often works the first time.

The template separates the tasks of
initialization, update, and output wiring.
The procedure "update_regs" becomes a distilled
functional description without any
wires or boilerplate spoiling the view.

I can simulate simple variable updates
in my head because the description uses
present values only. There are no signals.
