execution time-STM32F429zi

[SR.6]

i am just executing a for loop of 4096 time. But it takes more than 1 ms in stm32f429zi series. Clock frequency is 180MHz. How it can take that much time or whether it is executing some other function in back end.

Double check the frequency the core is clocking at.

Do a static review of the assembler code generated by the compiler.

Use DWT_CYCCNT to measure cycles consumed.​
