I am not a CPU designer, but my understanding is that the multiply instructions are usually the ones that are most complex single instructions, and in some sense determine the processor speed. (All you VAX guys can sit down; I know about your polynomial evaluation instructions, I'm just speaking generally). Trying to extrapolate great truths about data encoding from 10 lines of C will not be fruitful. Yeah, this is mostly off topic for networking, but as Joe Touch demonstrated, sometimes it matters: http://www.isi.edu/touch/pubs/sigcomm95.html -- Ted Faber http://www.isi.edu/~faber PGP: http://www.isi.edu/~faber/pubkeys.asc Unexpected attachment on this mail?
