implementation of an arbitrary precision integer librar for usage in application code

Altera_Forum · ‎03-27-2013

Hello,

This requirement is a part of my thesis and I was wondering have anyone occurred to do a similar task of this sort.

I plan to implement NIOS II custom instructions that will accelerate the speed of an arbitrary precision integer arithmetic

(since parallel operations can be done in FPGA).

As a comparative study I am asked to compare the speed of a normal arbitrary precision integer library function with the custom instruction.

Say an ADDITION of 1028 bit + 1028 bit data. (This can be implemented in NIOS II custom instruction using verilog modules and can be called

from the application C/C++ program using macros in system.h file). The same addition can be done in the application code using a

multiple precision library as well.

Issue is with respect to porting such a library to the NIOS II build environment.

MPIR is such an arbitrary precision library which can be built with a Microsoft Visual C++ 2008 edition solution.

Is there someone who is experienced in bringing such libraries to the NIOS II IDE build environment?

If so that would be a big help.

Any pointers towards this direction will be appreciated.

Thank You,

Akhil Kalathungal

Hello,

I figured out a user friendly library that can be moved easily to the NIOS II IDE build environment.

Now in my application code I can use those library functions and see the timing analysis using the altera timestamp libraries.

So I guess this question can be closed from my side.

Thank You,
