Vocal pitch detection

hi 
I would be happy and thankful if anyone can help me with the following

*what algorithm to use for vocal pitch detection
*is it possible to implement it in a real time system using TMS320C50
hoping for your reply

*what algorithm to use for vocal pitch detection

Most certainly US Patent 7124075 without any doubt (you are talking
about one vocal, right ?)

*is it possible to implement it in a real time system using TMS320C50

Sure it is, if it's simplified and optimized

Be sure to let us know about your success :-)

Be happy and don't stick your nose into the things that you have no clue 
about.

Normalized autocorrelation with upsampling to refine the result, or FFT 
harmonic peak matching.

It is hardly possible since TMS320C50 was phased out some 20 years ago.

Vlad,

Of course it's "possible".  The class notes go back that far!!

Vlad, weren't you going to be greeting Dmitry?

Don't exaggerate. This datasheet
http://focus.ti.com/lit/ds/symlink/tms320c50.pdf was last updated in 1996.
In the early 1990s the TMS320c50 was a major platform for V.34 modems, and
into the late 90s a lot of V.90 modems were based on it.

Does this processor still exist as a core, or has it been
completely sunsetted?
