https://ask.sagemath.org/question/39309/c-code-for-elliptic-curve-point-addition-and-point-doubling-arithmetic/?comment=39347#post-id-39347Well, time was an important issue also while formulating and typing the question...
(There is no mention of the ground field, the shape of the elliptic curve, etc.)
An answer would be "look at pari/gp", written in C for speed.
