• 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...
  • obtaining cycle count on cortex m7
    hi I have executed a cmsis dsp absolute function on cortex m7 (arm_abs_q7) and obtained the states as 860 ( as it indicates approximated cycle count). when i re-run the same function, i get the varying...
  • 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...
  • Instruction Count and Memory Access
    Hello, I was looking into the debug and trace features in the Arm Musca Board A1, which implements the Corelink SSE 200 IP (dual core Cortex M33, each with a three-stage pipeline), I came across the...
  • 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...
