Thesis Topic

Hi people,

I am a new bie to this forum and I am a graduate student, in need of a masters thesis project on Altera FPGA board.

My professor had asked me to check the possibility of modifying the NIOS ii core (32 bit) by adding some instructions so that an arbitrary precision

integer arithmetic library can be implemented. An application is, using that library we can implement an RSA encryption scheme.

I understand that it is possible to add custom instructions to the NIOS ii core and I see the tutorial link in the altera website.

Kindly help me here and let me know if I am going in a proper direction (one question I have in my mind is in any vhdl/verilog code, we can make a register

variable which can be of any number of bit size, which depends on how we define it. Even if the synthesized code may not go and fit onto a board, we still can have

simulations on the modelsim from the same module. So does it really make a good sense if I say an arbitrary precision implementation on an FPGA).

I am stuck at this thought, please advice me.

Any comments / eye openers are quite appreciated.

Thank You,

Akhil
