Hi,

I need to use a microprocessor for an application but I have only ever
used microcontrollers in the past so I'm a little unsure about the
whole microproccessor thing.

I need to take some serial data, perform some maths on it, then put the
new data out in serial form.  The maths that needs to be done invovles
exponentials to the power of 6, sin functions, sin^5 etc.  The
processor needs to go into a unit that will be hand held where current
drain is an issue.  Something that can be programmed in C would be
great.

Anyone got any pointers or tips regarding which family of
microprocessor would be suitable to use.  Or something to get started
on?

Cheers,

What do you mean when you say "microcontroller" and what kind of speed do you need to achieve?

What you describe could easily be done with an 8051, or any other 8-bit microcontroller given sufficient time and enough program memory -- you could probably even keep it to 256 bytes of RAM if you didn't try for an OS.

Without further detail you need something from 8 to 64 bits, that will consume between 0.01 and 1000 watts of power, with between 128 and 128000 bytes of RAM, etc., etc., etc.
