• Cortex M3 : what determines the cycle count for a variable cycle count instruction?
    I have looked at the cycle counts for the Cortex M3 instructions at http://infocenter.arm.com/help/topic/com.arm.doc.100165_0201_00_en/ric1414056333562.html . Some instructions are listed as taking a...
  • measure clock cycles consumed by a code in Cortex-M
    Hi, I want to measure/profile no of clock cycles takes to run a c++ code (say in cortex-M). How can I do this?
  • 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...
