• Cortex-A9 PMU cycle counter not always incrementing at CPU frequency?
    Hello, I want to benchmark my program running on Linux on an Altera Cyclone V SoC board, but it turns out that the values returned from the ARM Cortex-A9 PMU cycle counter suggest that some sort of CPU...
  • PMU in arm11 results
    Hi, I am programming raspbery pi model b ARM1176 bare metal (in assembly and c). I need to calculate the clock cycles used to execute an assembly code. I am using the following code for PMU counter: ...
  • Cortex A9 CPU self-tests
      Hi! I am currently working in a project with a Freescale i.MX6 (Cortex A9) board. The system has to be certified against the ISO 13849 standard and my job is to implement software diagnostics in accordance...
  • How to configure Cortex-A57 PMU
    I asked this question in a different community space but it seemed like this is a more appropriate home. I'm trying to configure the performance counters for the Cortex-A57 and I'm very confused. The...
  • Can we use PMU(Performance Measuring Unit) on Cortex A8 for calculating cycles on Simulator without hardware?
    ARMv7A family members will have PMU on the processor. Using this PMU, we can access cycle counts. Can we relay on this using the simulator?
