• VTOR: offset address configuration
    Core: Cortex-M4F Do I need to configure vector table offset address to 0xnnnn_n 000? In case of 0x3080(Flash region), the program jump to unexpected code. I think it is caused by mismatching between vector...
  • 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...

  • Question on clock gating for AHB -lite bus matrix for CM4 based system
    Joseph, We are using CM4 and AHB -lite bus components from ARM system development kit. We have 3 different AHB masters in the system, including CM4. I am wondering if we could use HTRANS from each master...
  • 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...
