• 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...
  • Accurate cycles measurement
    Dear experts, I am currently trying to measure the cycles required to context switch between two linux processes and the cycles required to world-switch between two linux VMs running above a thin bare...
  • flush_cache_all() API consuming 200+ microseconds.
    Is this is normal behavior? Or suggest any other alternative. Since flush_cache_all() consuming major portion of total execution time, I couldn't proceed with this. Is there any other way, which helps...
  • 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...
  • Understanding of the clock cycle activity for LPC1114
    Hello, I am now working with the LPC1114 which utilizes the ARM CORTEX M0 architecture. I have one question about the instruction set summary of the ARMv6M Thumb instruction set. I want to know what...
