OT : Approximate / fast math libraries ?
[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]
Hi,
I have a number crunch application that is starting to hit bottlenecks
in standard maths functions, like log, exp sqrt etc. Thing is, in many
places I don't need much precision, so was wondering if there was
anything I could do, like use a different library or enable some gcc
options (currently using -O2) to speed things up.
Does anyone have any recommendations for fast maths ? search around on
the web I've found a lot of references to fast / approximate math
libraries, but nothing obvious.
