I guess I am one of the few that try to run speex entirely from internal RAM and the fact already forced me to move from BF531 to BF533. BTW, the above exercise in deep philosophy at shallow shores shouldn't be taken too seriously ;) >About the inline assembly, I was under the impression that the syntax >was compatible.
