I am a bit confused by your comments, though: I think in this case you aren't going to deal with cache misses. The likely performance issue is branch prediction failures.

And clipping should be able to be handled with conditional moves, which shouldn't (in theory) create instruction pipeline issues. But in terms of performance you are doubling the number of tests if there are two different thresholds. Anyway, without seeing a profile this is moot.


In a world where people spend more on ADC/DAC hardware than on their computer I can't imagine they're going to be keen to downgrade fidelity (even if theoretical, cf other discussions here) for the benefit of a few extra CPU cycles.

Ross.
