Mops(macro-ops). uops(micro-ops)

Hi DANNYWW,

I think that as per Zenon (Zhilong) Xiu 's answer, instructions (insts) have not been decoded yet, and MOPs are what you obtain after decoding the instructions. Logically speaking they are very close and the distinction is more a matter of representation inside the processor.

The µops are different; quoting the Arm Cortex-A78 Core Software Optimization Guide:

"A MOP can be split into two Micro-OPerations (μOPs) further down the pipeline after the decode stage."

For example:

"Stores μOPs are split into address and data μOPs."
