Hello to everybody!
This is my first post in this forum.
I've been using Blackfin for a couple of years (and I developed some project with ADSP-218x before) but I've never been able to find a nice Digital Filter Design tool that gives filter coefficients in the format required by Blackfin DSPs.
Usually I use fract16 data type, and most of the Digital Filter Design tools I tried don't provide an option to consider quantization...
I think that the old FilterExpress from Systolix is very, very good to design FIR filters.
For IIR ones, it doesn't give coefficients in two vectors a and b as the Blackfin expects, but only as a bi-quad cascade.
Does Analog Device supply a free tool for this purpose?
