Digital Filter Design tool for Blackfin

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?

 

Best regards
