Here is the step-by-step procedure:
1) BUY a decent COMPILER
2) Type in the EQUATIONS- use double and #include math.h for
trig (if using C)
3) RELAX and have a nice cold BEER (or a warm one if you'd
prefer) It will work just as it worked on your PC.
There is NO need to devote hardware to this- the chip described is
a pre-programmed microcontroller aimed at a non-professional
market IM(NS)HO. A $5 US chip can burn 50% of its bandwidth
(say 4MIPS) running floating point math in the background
while walking and chewing gum with every port pin. It's a no-
"it's the network..." "The Journey is the reward"
