Hello,
I am developing a program in the S32DS 3.5 RTD 4.0.0 environment.
I would like to compare the CPU load when using DMA vs. Interrupts. Does S32DS support such functionality?
For reference, I am working in a bare-metal environment with an S32K314 MCU and a PE Micro MULTILINK LC debugger.
Thank you.
Thank you for answer @davidtosenovjan
I found that the Data Watchpoint and Trace (DWT) feature in the ARM M7 architecture can be used to measure function execution cycles.
Could you provide an example of how to use DWT for cycle measurement on the S32K3XX series?
I am afraid there’s no such feature in S32DS and there’s no hardware support in ARM core on S32K devices.
