QUESTION

Micro-optimizing C code for ARM

Asked 2017-Mar-01 at 09:28

Apparently it's true that on ARM cpus, division is 10-100x slower than bit shifts. On this site it is stated that this can be solved in a number of ways. One of them being look-up tables for small problems, which is fine and standard. But listed was also replacing division with multiplication by a fixed-point reciprocal followed by a bit shift (so that x/3 becomes (x*6) << 1 etc) Another was replacing (x % y) > z with x > (z * y).

I'm far from an expert, but this sounds really odd to me. I mean, if you're using a modern compiler, wouldn't this be exactly the kind of thing that is optimized for you?

unsigned int fun1 ( unsigned int a, unsigned int b )
{
    return(a/b);
}
unsigned int fun2 ( unsigned int a )
{
    return(a/2);
}
unsigned int fun3 ( unsigned int a )
{
    return(a/3);
}
unsigned int fun10 ( unsigned int a )
{
    return(a/10);
}
unsigned int fun13 ( void )
{
    return(10/13);
}
