[ydl-gen] Mplayer on the PS3

[Warren Nagourney]

Imagine what it would be like when (and if) they start adding some of  
the spe's into the mix. I have found that scalar code runs  
significantly faster on an spe (providing it fits into the 256k LS)  
than on the ppe - a factor of 1.5 or so. A fairly CPU intensive  
raytracing program (single precision floating point) that I wrote is  
equivalent to a 1.7 GHz G4 on an spe and a 1.2 GHz G4 on the ppe  
(same level of optimization). I believe there is a German developer  
who has written a flash player which uses several spe's and works  
very well. Let's hope that more amateur developers start writing  
accelerated apps for the ps3 - perhaps with the European launch  
things will pick up a bit.
