Hmm.. In the Atmel ATMega128, I did some thermal compensation code that
might be similar to what you're getting to.

For each input parameter, I built a table of constants and used the AVR's
FMULT (fractional multiply) to compensate.

If I remember right, there were something like 16 variables involved, and 16
entries per variable.

The Mega AVRs also allow you to read and write code space a word at a time,
so you could easily over-write the table values with something else.

Overall horsepower is better than a PIC at equivalent clock, most
instructions are single clock cycle, some two, and there is no
paging/banking etc to deal with.
