MIPS and MOPS

Hiya


MIPS stands for million instructions per second. I assume word
instruction here means MOPS means million operations per second.

Now programmer writes a command ( say LDAA #16 ) that adds two
values.

a) Is This command called instruction or operation?


b) If it is called instruction, then CPU will break down this
instruction into a bunch of smaller steps, called operations?!

But if command is called operation, then CPU will break down this
operation into a bunch of smaller steps, called instructions.

Which of the two is correct?


2)
Why are MOPS and MFLOPS more correct ways ( compared to MIPS ) of
measuring the speed of CPE?


Thank you
