Hi,

In order to handle performance issue, i require assembly code for sqaure root function that will boost the

over all system performance providing better results.

There are a few important details missing in the question.
First, for which processor is this, for a S08 or S12 (or XGATE or RS08 or CF)?
Then on which kind of values (floating point, int, long, limited value range, complex numbers,...)?
ANSI C provides a floating point one only, so if you need an integral one, then
here's a C implementation by bigmac using a new Newton algorithm:

Thanks for the info.,

This code is required for flexis AC series of controller for S08 as well as CF processor.

It is basicly used for handling floating point numbers.
