Long integer library for C2H

[Altera_Forum]

I have a little trouble to find a good long integer library 

that work with C2H. Some libraries use floating point arithmetic (e.g., numerical recipes, slow on NIOS) or other (e.g. LIP) do not compile at all with C2H. I would like to speed-up the RSA algorithm but could not find a good working long integer library so far.:confused:

Take a look to AC Data Types from Mentor

Thanks -- I downloaded the package and the Mentor package seemed in C++, so it is not really supported by C2H, or could you used it with C2H? C2H acceleration I have seen were always using plain C not C++.
