I have a trained a baseline regression model as starting point for further optimization.
Before I proceed I was checking the RAM, FLASH and Latency for different boards.
When I select Nordic nRF52840 DK (Cortex-M4F 64MHz) I obtain:
When I select Arduino Nano 33 BLE Sense (Cortex-M4F 64MHz) I obtain:
If I am correct both (DK and Arduino BLE) have the same MCU, the nRF52840.
Why is there a difference in latency (163ms vs. 232ms)?
I also notice in case of nRF52840 DK there is an increase in latency (float32 vs. int8), for Arduino there is a decrease. I would expect a reduce in latency in case of quantitation, or am I wrong?
Do I overlook something?
Is it possible to provide some background about the latency calculation so I get a better understanding.
Thanks for the feedback.
