RNG tester

Former Member

Dear All!

I am going to create random number generators tester on my ZedBoard. The idea is that I will be creating different RNGs in PL. It's output (quite substantial amount of data) will be stored in RAM and then statistically analysed in PS with Dieharder set of tests. This set of tests is open source and is available as C library. It uses GNU Scientific Library.

Should I try to do it baremetal or create some minimalistic full blown Linux? I gues that "baremetal" approach would be the best because of memory usage, but I am not sure if I can manage it.

PetaLinux, Debian/Ubuntu or something created with Yocto is the best way to go?

Best regards,

Zygmunt

    Thank you.

    Generating pseudorandom numbers in FPGA in different ways is not a problem. The problem I have is how to transfer it effectively from PL to PS.

    I've already created AXI Streaming periferial producing random numbers and compilled Linux (Yocto did the job) on PS. I've installed DieHarder tests. The only problem remaining is how to transfer substantial amount of data (for example 10 million 32bit numbers) from PL to PS to access it as a file (could be file on SD card mounted in Linux, memory mapped file or anything that will do the job).
