Thanks Jaesung! This is actually something that's defined by the Arm Cortex M platform, so I don't know the definitive answer. From looking at the documentation though, it appears that each tick represents one cycle count. So, for example, if you have a CPU clocked at 48MHz, each tick will represent 1/48,000,000 of a second. This is only a guess though, so you'll need to check with the datasheet of your hardware or its manufacturer to be certain.

Hi all,

I am wondering what is the value of 1 tick in seconds for the Cortex M generic micro_time.cc file.

Link: https://github.com/tensorflow/tflite-micro/blob/main/tensorflow/lite/micro/cortex_m_generic/micro_time.cc

I wanted to know what does 1 tick represent when I use this file to run micro_profiler.cc and get the ticks for my model.

Thanks
