Does anyone have an example of dtmf decoding using a SHARC dsp? How about a Goretzel routine written for the SHARC? Thanks for your help.

When I needed this, I started with ADI's app note for the older 16-bit DSPs and modified as required. I can't give you the code I came up with as my company owns it. :-( "Steve Holle" <sholle@link-comm.com> wrote in message news:ba83847d.0405211442.4c625367@posting.google.com...> Does anyone have an example of dtmf decoding using a SHARC dsp? > > How about a Goretzel routine written for the SHARC? > > Thanks for your help.

The old app note for 21xx could be a good starting point, and it wouldn't be to difficult to modify the code therein provided to work with SHARC's 32 fixed point mode of operation, or even in floating point mode.
