# Calculate Stages in Non-Pipelined Processor

I have tried to attempt a question where I have to find the number of stages for non-pipelined processor(8085) for below program :-

MOV #40, R00
MOV #50, R01
MOV #60, R02
SUB R02, R01
INC R01
SUB R00, R02
HLT


What will be the no. of stages and there list here?

• Think about it: How are we supposed to know? It depends on the processor. You know which processor it is, we don't. – gnasher729 Jun 2 at 7:28
• @gnasher729 It is 8085 processor. – nbalodi Jun 2 at 9:00
