Hi!
I see, that this subject is good for biig discussion :]
I've read all informations... I'm sure they will help me - as I'm just a
begginer in that subject.
1. There is no problem to write it in C. I just used to assembler, and
so thought that such simple program could be written in asm - nei

Whoah, I didn't know that!

Yes, I have to admit that day by day I love it more :)

I got nice speedup to my FIR code by using inline assembler for e3dnow
optimized version... Will see how much improve

I think you should consider using RT-Linux where you can make your realtime
task run at predefined scheduling rate.
Schduling rate of 1 MHz is quite high, interrupt latency and scheduling

Odd .. I'd expect you could get away with using a timer or something,
but those timers may not be very good at PWM generation ..

That you can't buy this is no excuse as it's online on the O'Reilly site
(the entire book is online in pdf and html formats). Don't you love linux/
open source??

Hi!
I'm making D-CLASS amplifier for Linux platform...
I have to connect computer to radio at school, that would play music on
breaks.
The computer would be connected to a radio speakers-network thru a
D-class amplifier
built on few mosfet transistors and output power of few hundred of
watts.
