for Cortex-M0, M3 and M4, I can find the execution time in their Technical Reference Manual > Programmers Model > Instruction set summary 里面查看

but for M7 It said that I should go to <ARMv7-M Architecture Reference Manual.>
“The processor implements the ARMv7-M instruction set and features provided by the ARMv7E-M architecture profile. For more information about the ARMv7-M instructions, see the ARMv7-M Architecture Reference Manual.” -----《ARM Cortex-M7 Processor Technical Reference Manual》Programmers Model > Instruction set summary > Binary compatibility with other Cortex processors
But in <ARMv7-M Architecture Reference Manual.> I still can't find it. what should I do?
thanks for your reply. I am still a little confused. what's the dual issued? because all the other uP has given the cycles table except M7. Is there any official explanation for this issue?
you said benchmark is more useful for M7, do you mean that 'adding sequential instruction timing' is also more useful for other cortex device?
Thank you very much
