use gmp on microcontroller freescale coldfire

[Drößler Tobias]

Hello gmp-friends, 

i want to evaluate if it is possible to use your gmp lib on a freescale microcontroller  "coldfire" used in an embedded platform.
Its derivated from Motorola 68000, 32 bit machine, but RISC   ==>  http://en.wikipedia.org/wiki/Freescale_ColdFire 


We need it for checking elliptic curve digital signatures  ( so only integer arithmetic /mpz ) ...  as background information. 
We have only static RAM but a heap and malloc/free functions.

So I ask me if it is possible to use your lib on such a device, may someone have experience that way ? 
How can I check if its working?  Or do you think more like this: "no way to get this work" ?
May someone has an alternative to calculate with such big numbers on an embedded cpu. 
 
Thanks for your attention.
 
nice regards 

Tobias
