• Is offset of 30 in load and store instructions shows an exceptional case?
    Hello to all, I am working on ARM Cortex-M4 and the memory arrangement is the little endian. I have started working on the memory instructions and for that purpose, I have chosen the offset addressing...
  • What happens when offset value becomes 30 in case of load/store operation
    Hello to all, I was looking at different offset values for both load and store operations. Since due to little endian arrangement, the memory looks something like this to processor: Byte[0x23],Byte...
  • 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...
  • RFFT CMSIS-DSP - Fluctuating index
    I am using the Cortex M4 with CMSIS 5.4.0 DSP library. I'm using the arm_rfft_f32() function and the max_arm_f32() function to compute the maximum frequency bin of injected pure sine wave with an external...
  • How the current consumption is affected by instruction address
    Hello to all, I am willing to know the variation in the current consumption due to the instruction address. Therefore I have performed two experiments, first time filled the pipeline with a 32-bit instruction...
