How to generate BT9 format traces?

[rxzzp666]

Hello, I am currently doing some research on branch prediction and need to generate the trace provided by CBP. However, all the download links on the CBP official website are no longer valid, and I don't know how to generate BT9 format traces. Can you please tell me how to do it?
I apologize for my lack of knowledge. Good luck to you!

Hi @rxzzp666

Thank you for your interest.

@craymichael has uploaded the files, and provides a download link in his repo: https://github.com/craymichael/CBP-16-Simulation?tab=readme-ov-file#installation I suggest you download them from there.

Concerning the BT9 format: I am unsure where to find a comprehensive documentation, but you can start with the bt9_reader, that built the skeleton for the CBP-5 challenge.

Our version is modified (main.cc) to extract the branch_address and the branch_taken information, which we used to validate our implementations.

Good luck with your research and feel free to PR any documentation that you think would be helpful to others.

Regards
Andreas
