style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">The 42 MIP number was from my post
of 24 May, and it was for C55x and Speex 1.1.8. I tested 1.1.10 yesterday,
and the number went down very slightly; it was just over 41 MIPs peak measured
in 20 ms blocks on MALE.WAV, for encoder/decoder loop, 8kbps
narrowband with minimum complexity. C54x was just awful in comparison
(>200 MIPs, not enough for real time), and I abandoned that family and
switched to the C5509A. At least one other user has made some
optimizations for C54x and gotten the MIPs down some, but the C55x family seems
to like Speex a lot better (32-bit math support is more efficient). I had
promised Jean-Marc to make a reference build for others to look at, but I have
not got around to that yet. I can send you the .pjt and .cmd files that I
used, if you like.</SPAN></FONT></DIV>
