Lookup Tables

Hello,
I am writing a program that has to multiply the incoming DAC data on the ADuC812 8051 by a sixth order polynomial equation. I was wondering if anyone had any information regarding using look up tables or any good sites as I have not found the internet useful.
As I have to multiply the equation by possibly 4096 steps is there a way to cut down on the possible number of values?

Thank you,
Marcus

  • mathematically, you are trying to compute y = f(x);
    a lookup table implementation simply treats this as

    y = f[x];
    You can easily compute the values for the elements of the array f (ie, the lookup table entries) using Excel or similar.
