Hello!

I know a library that fit your description.

TTmath is a bigint/bigfloat library for numbers that are only allocated on the stack, using with C++ template and with some asm optimisations :
http://www.ttmath.org/ttmath
under the BSD licence (a kind of you-can-do-allmost-all-you-want licence). 
Since the time I know it, I have not needed other bigint or big float library (even GMP). Anyway, I think a potential Soc student should at least check it for reference.

Best regards,
