In my real world case the target was 32-bit microcontroller-class soft
core without hardware multiplier running at 100 MHz. Also, we should not
forget that a single ECDSA signature validation contains plenty of
ipow() steps. Right now I don't remember how many.
I didn't try algorithm presented here by Bart, but tried something that
can be seen as its mirror image.
wword ipow(wword a, wword n)
{
if (n < 2)
return n == 0 ? 1 : a;
wword y = ipow(a, n/2);
y *= y;
if (n & 1)
y *= a;
return y;
}
Please, treat it as a pseudocode.
Real code was more complicated, with function calls instead of *
and recursion was manually converted to iteration.
The result was slower than the following (pseudo) code:
wword ipow(wword a, wword n)
{
wword y = 1, p = a;
while (1) {
if (n & 1)
y *= p;
n /= 2;
if (!n)
break;
p *= p;
}
return y;
}
I didn't try to investiagete reasons for the difference.
