If you have to do this in software, Goldschmidt's algorithm parallelizes a lot better than Newton-Raphson, but isn't always general-purpose (IIRC). It uses a multiplicative update rule instead of an addition like NR. Division, square root, and inverse square root all use that algorithm under the hood (at least in AMD and IBM processors). |
