Hi Brian,

some numbers have been shared in this presentation from a while ago:

Microsoft PowerPoint - TF-M Performance Improvement in v1.5.0.pptx (trustedfirmware.org)

I believe there should be more updated numbers on more recent versions, but I don't seem to find them, maybe somebody else with more updated benchmarking can help here.

Thanks,

Antonio

Subject: [TF-M] SFN vs IPC partition with IPC backend

If using IPC backend, how much performance and/or memory savings is there when using SFN vs IPC partition model?

I saw FF-M v1.1 recommended SFN partition model but it was not clear to me why it was preferred.

Regards,

Brian Quach
