Any high-precision or arbitrary-precision integer arithmetic library for TMS320C55x ?

s_xczp s_xczp

Hi, all.
I am using TMS320C5509a for data processing containing large integer operations.
The integer members may be up to 100~200 bits length.
According to my knowledge, there are some high-precision or arbitrary-precision integer arithmetic libraries for x86 CPUs used in Unix or Windows systems. But I have no idea about such libraries for DSPs, e.g, TMS320C5509a or TMS320C5509.

Can anyone with kindness help me?

Hi,

I haven't seen a TI-provided library for C55x that covers arbitrary-precision. I have seen recommendations to port GMP if such support is needed.

According to your suggestion I have downloaded GMP. But TMS320C55x is not one of the suppoted CPUs of GMP. Can you suggest me other libraries?

Thanks in advance

As indicated in my previous post, the suggestion was to port GMP. It is not natively supported and would require porting to C55x architecture.

Hi,

I am developing the project as a stand-alone system, no connection to other CPUs. TMS320C44x is just the only one CPU in the system. Indeed, I only need +,-,*,/ and compare of large integer or multibyte integer operations. Maybe some small routines suits the situation. But I have no idea of it.
