Where to find the execution cycles of Cortex m7 instruction

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

http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0432c/CHDCICDF.html

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?

  • Binary compatibility with other Cortex processors means that you can use instruction execution time (in cycles) for Thumb instruction set from previous technical reference manuals of ARM Cortex-M3 or ARM Cortex-M4. Read more about compatibility in ARM Cortex-M7 Processor Technical Reference Manual, chapter 2.3.1. Binary compatibility with other Cortex processors. ARMv7-M Architecture Reference Manual includes more detailed information about ARM and Thumb instruction sets.
