• Get current active interrupt priority
    Hi everybody, We are working on a simple priority RTC (run to completion) framework for the Cortex M3/M4. Thanks to the NVIC/BASEPRI, we got most of this functionality for free but we want to extend it...
  • 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...
  • I want to know priority of Cortex-M3 processor
    which interrrupt priority is higher? systick vs IRQ(external timer) because In my case externl timer is higher then systick. I saw that during processing in systick ISR, but suddenly pc jump to...
  • Difference in the current consumption for different register place for few instructions
    Hello to all, While working on different assembly instructions, I have come across a very different problem of the register's place. For example: SBC r11,r7,r11 : 3.0217mAmps but SBC r11,r7,r7...
  • Current Variation due to Functional Unit activation or deactivation
    Hello to all, I would like to measure the current variation due to Functional Unit activation and deactivation. Can anyone help me out with the assembly program or the code through which I can measure...
