As a general rule ARM chips have much smaller caches than Intel. 5 Use SIMD NEON when possible... have smart precache logic the way that modern Intel chips do. 7 Don't trust the compiler to generate good code. Look at..

Different math rounding behaviour between Linux, Mac OS X and Windows http://stackoverflow.com/questions/1961442/different-math-rounding-behaviour-between-linux-mac-os-x-and-windows I can't speak to the implementation in Windows but Intel chips contain 80 bit floating point registers and can give greater..
Best way to detect integer overflow in C/C++ http://stackoverflow.com/questions/199333/best-way-to-detect-integer-overflow-in-c-c a better way of testing for overflow I know that some chips have an internal flag that is set when overflow occurs but I've..
When is it worthwhile to use bit fields? http://stackoverflow.com/questions/4240974/when-is-it-worthwhile-to-use-bit-fields some emulator code and it looks like the registers for the chips are not being implemented using bit fields. Is this something.. when bit fields are used ie firmware to put on actual chips etc Thanks all R c c bit fields share improve this question..
