TMS320C30.  It is a 32-bit floating point DSP; it does not resemble
the TMS320C2x (20 or 25) chips in any way, and it would have been more
honest for TI to make an unrelated name for the chip.  It does a
floating multiply in parallel with a floating addition (the
destinations can be different, not just a multiply-and-accumulate) in
a single 60ns cycle, and like most DSP chips, it has zero-overhead
loops.  Integer multiplies are only 24x24 bits (32 bit result).  It's
in about the same league as the DSP96000 in terms of performance,
though I don't know as much about the 96k as about the C30.  By the
way, can you get 96000's yet?

By the way, Todd Day (todd@ivucsb.sba.ca.us) is now conducting the
official vote for the creation of comp.dsp.  Send yes votes to
yes@ivucsb.sba.ca.us and no votes to no@ivucsb.sba.ca.us.
