[tremor] Current Performance?

[timmy brolin]

ARM710, is that the same thing as or similar to ARM7tdmi?
Then I'd have to say no. At least I'am pretty sure you can't run tremor at 44k1 stereo in realtime on a 40MHz ARM7tdmi.
Things have improved indeed, but I don't think the speed of tremor has doubled yet :) (originally it required a 74MHz ARM7tdmi you know)

Subject: [tremor] Current Performance?

<p>I've been monitoring the group for a few weeks and I checked the
archives, but I haven't seen this come up for a long time and it
sure looks like things have improved a bit since then.  So, I'll
ask it...

How much CPU does it take to do stereo 44k1 s/s decode?  I'm 
working on getting Linux to run on a Webpal (40MHz ARM710 core).
Can I expect to be able to get ogg/vorbis files to play?  It
would be nice to drop a NIC in one of these, set it next to my
stereo, and stream Ogg files from my file server--or a web
radio site, etc.

Is there any estimate of what the minimal CPU to decode to a buffer,
from a buffer is?  I can't hold I/O agains the code as the cost
of that will vary too much from platform/OS to platform/OS.

Thanks, and thanks for Tremor. :)

Cheers,
David
