Dear All,

Can anyone please let me know the overhead (cpu cycles) of checking a memory access as described in figure 2 of this paper: https://software.intel.com/en-us/articles/innovative-instructions-and-software-model-for-isolated-execution

To break it down, I'd like to know the cpu cycles spent by each step in the figure, such as cpu cycles spent by doing EPCM checks (suppose there are 10 entries)

Thank you very much for your time.
