• 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...
  • Cycle count for a subroutine on Cortex M33
    Dear All, I am running a led toggle sub-routine in infinite loop for Cortex M33 on MPS2+ FPGA Board, want to calculate cycle count in one iteration. ToggleLED_Subroutine PROC LDR R0, =0x40302000...
  • 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...
  • Obtain CPU Temperature in Kernel
    Dear All, I am using a raspberry pi B+ that uses a Broadcom BCM2837 SoC with an ARMV8 processor. I want to get the cpu temperature in a Linux kernel file. Like in x86, I can use rdmsr_on_cpu function...
