How many clock cycles does it take to switch working states by CPS #n

Hi everyone! I usually use the instruction CPS to switch working states form PL1 to PL0, or switch between PL1s. How many clock cycles does it take? Based on Cortex-R5, will it take a long time？ ...
How many clock cycles do SVC/PUSH/POP/SRS/RFE insturctions take to execute on Cortex-A8 processor?

I'm trying to count the cycle timing of my program in hand. I read the ARM Cortex-A8 R3P1 Technical Reference Manual: Chapter 16. Instruction Cycle Timing, but I couldn't find the cycle timings of SVC...

why does LDR takes two cycle to be executed

Hello everyone, I am currently working on a cortex-M0 microprocessor(LPC1114). I have looked through all the possible instruction descriptions but I did not find anyone of them explaining why some instructions...
