I just wanted to suggest to the OP that the sort of question he was 
asking was one that people have been known to pay for the answer to.  I 
suspect that there are other report-writing entities that have similar 
services, too.  The question sounded like homework to me, but maybe not.  
I try to be helpful without doing the hard work myself :-)

My old e-mail address in the FAQ has finally been decommissioned.  I 
suppose that I should ask to have it removed.

Cheers,

ADI have several other DSPs besides the Blackfin, so they probably have a 
nice comparison page that compares them all.  That'd be a good start, I 
suppose.

Then just extend that to include all of the DSPs by all of the other 
manufacturers.

Build a big table that compares things like number and size of internal 
registers, size and bandwidth of on-chip and off-chip (if any) memory, 
how many multiply/accumulate operations they can do per cycle, and of 
what length, what addressing modes they support, and how well (or not) 
these correspond to both C compiler support and common DSP-kernel idioms/
patterns (the two are *not* the same).  There are lots of other things 
that you could compare, of course: peripheral sets, price, clock speed: 
it's a many-headed beast.

Failing all that, I believe that there's at least one company (who's name 
escapes me at the moment) that writes reports of this sort 
professionally.  They'd probably be happy to sell you one.

hi friends,
i have been given an assignment of comparing blackfin with other dsps. so
which processors should i include (i.e. which processors are comparable
with blackfin).do reply,
thank you,
