Buying a C6711 DSK

Hi everyone,

(I hope this question hasn't been asked elsewhere on this website. My
apologies in case it has been.)

TI has discontinued C6711 DSK in favour of C6713. Does someone know any
place where I can buy C6711? I'll go for C6713 if its impossible to buy
C6711. It's just that some of my friends/colleagues have C6711 and it would
be easier for me to get started on this DSK. (I am almost a complete
beginner!). I also have Dr. Chassaing's book and it uses C6711 for its
examples.

Furthermore, I read somewhere that it should be possible to run
fixed-point algorithms on a floating-point DSP such as the ones on C6711/13
DSK. Can someone please confirm whether it's true or not? I would like to
start with floating-point but would also want to do some fixed-point stuff
later.

Thanks in advance.

Starting with the 6713 will not be much different than the 6711.  You
use the same development environment, the boards have similar
peripherals, etc.  We have had students easily move from 6711 to 6713
boards.  I would go with the 6713 EDK it is more stable than the 6711.

Yes, you can do fixed-point on these processors.  Some fixed-point
only processors will have some additional instructions but you should
be able to do what you want.  Develop a real-time algorithm in
floating-point and fixed-point and compare / contrast.
