Hello everyone,
I developed a bare metal system for Cortex-A15 Versatile Express board. I used Fast Models to run/debug the system and now I want to perform some performance test to measure latencies by counting elapsed cycles with the PMU. I noticed that ARM Fast Models uses a fixed CPI=1 for all instructions and that Timing annotation is not supported for the FVP_VE Models. Is this true?
Since I do not have the possibility to test the System in a real Hardware, are there other ways to accurately count elapsed cycles?
Thanks a lot in advance.
Any kind of help will be very appreciated.
Giò
