Hello,
I am looking to do a moving average function using DSP instructions of ARM Cortex M7. Unfortunately I couldn't find a direct example. My goal is to have variables for
- the sum
- the new value
- the oldest value
Then the algorithm is sum = sum + new value - oldest value and average = sum / ( number of values between oldest and new), ie two instructions
I think instruction UMAAL could be good for this, I found it in instruction set summary, but it is not in CMSIS library. Why is that? Where can I find details about it and how can I create my own C asm caller?
Thanks for any help and hints or other ideas on this topic, I hope it also helps other developers.
Kind regards
Martin
