You've completely missed my point.
MP3 compression, video encoding and sound editing all are *highly* suited
to Crusoe.
lets take MP3 compression.
PCM --> FFT --> compress --> MP3
Unless your mp3 encoder has enormous amounts of self modifying code (shudder),
the FFT and compress loop will get executed repeatedly.
David, if you think that

you really need to study basic computer science.
BTW what is this MP3 encoding benchmark. Are we comparing a 'SpeedStepped'
P3/Celeron vs a Crusoe or not. How long can you encode MP3's on an average
Intel laptop before the battery dies?
Sorry for the flamage, but you seem to be wilfully ignorant in this case.
Cheers
