#98573 - Speed is not everything!
Responding to: Jan Waclawek's previous message
Jan Waclawek said:
No - if I'd C, and had critical routine, I'd use assembler only if unable to make it fast enough in C

My point here is not for when maximum speed is critical, but for when you just need to be certain of the timing.

The classic example is, of course, the software delay loop; for a precise delay, you must use assembler - not for speed, but for precision!
