Problem is, this goes into a tool library that runs background services which should have lowest possible impact. If I find something ready made that reduces time by 5%, I'm fine. (If I have to code two days, it's not worth the trouble)<br />
<br />
The data conversions are unavoidable, since they are interfacing different components. <br />

(I think the biggest time easter will be running through the 128K*8Bytes of memory anyway)

umm... I can't close it with points refunded, right?<br />

while grg99's comments are valid, they don't answer the question at all.

I am looking for fast conversion routines that convert between arrays of int (different types|widths), float, and double. <br />
They should use platform-specific instructions (e.g. SIMD2) if available, or fall back a portable solution otherwise.<br />
<br />
I am *not* looking for loose links/snippets how to do individual conversions. <br />
<br />
Any suggestions?<br />
TIA <br />

C++ is an intermediate-level general-purpose programming language, not to be confused with C or C#. It was developed as a set of extensions to the C programming language to improve type-safety and add support for automatic resource management, object-orientation, generic programming, and exception handling, among other features.
