Number Scaling

Hi Dave,

Thanks ..

The thing is that I have a random Integer input in the 0 - 579 range, without any fractions, simply integers :) ...(xmin-xmax)

This need be scaled to the -1 to 1 range (ymin-ymax) following this rule

y = (ymax-ymin)*(x-xmin)/(xmax-xmin) + ymin;

In my application it is:

y = (2*x)/579-1

So based on what you said, to implement the above formula, all I need to do is shift my integer 10 bits to the right?? and then subtract one?

Note that the following Hardware stages are in signed fixed point format with <S, M, N> = <1 sign,5 integer,10 fraction>, is the result readily available for use in the following stages?? or scaling is further needed?

Thanks
