I'm trying to run a low latency kernel and audio
applications on a
crusoe processor laptop.
Yes, I'm crazy.
You might want to take a look at the following:
http://www.mindcontrol.org/~hplus/aes-2001
In slide 5/6 three different processors are compared and the 400 MHz
Transmeta Crusoe is said to have a 1000 us interrupt latency whereas
a 600 MHz Intel Celeron processor has a 80 us interrupts latency,
both running BeIA/BeOS. This is probably related to code morphing.
Maybe more recent Crusoes aren't affected.
