Question about the Pipeline, clock cycle and machine cycle in Cortex-M Series.

Recently I'm learning the implement of ARM cortex m core in order to optimize my software to be more efficient and be easier to predict its execute time. But now I'm confused about the clock cycle, machine...
Measuring Cortex-M4 instruction clock cycle counts

I'm trying to find a reliable method for measuring instruction clock cycles on the STM32F429 MCU that incorporates a Cortex-M4 processor. Part of the challenge is that although the core CPU has no cache...
Where can I find the device-specific JTAG instructions for Cortex-M3?

I'm trying to communicate with a Cortex-M3 based microcontroller (LPC1769) through JTAG. I already have the hardware required, and have managed to get an example program to work, but to progress further...
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...
Interruptible Instructions on Cortex-M4

The ARM Cortex-M4 Processor Technical Reference Manual states: To minimize interrupt latency, the processor abandons any divide instruction to take any pending interrupt. On return from the interrupt...
