Number theory and FPGAs

[555lin]

I 'd like to learn to make cryptographic projects involving
a great part of number theory , especially in assymetric cryptography.
Could anybody provide some examples in VHDL code or methodology
of implementing these things?

Hi,

You would better make a search for good ebooks about this subjects. I saw many of the on Internet (emule).

you should know some differences between vhdl and programming languages (for example C).
when writing a program in C, you don't care how many +-*/ you have. you can compute 784/129. but you have some restriction in vhdl IF YOU WANT TO WRITE A SYNTHESIZABLE CODE. (to download it to an fpga, for instance)
if you want to only simulate your code, you can use functions in ieee MATH_REAL and MATH_COMPLEX packages (ieee std 1076.2). plus functions of arith, signed and unsigned packages.
you can find ieee 1076.2 standard here:
