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 
ADD R02, R01 
INC R01
SUB R00, R02 
HLT 


What will be the no. of stages and there list here?
That processor should come with a manual. If yes, you can use the information in the manual. If no, you can google for the manual, like "8085 manual". The number of cycles and states for each instruction are in chapter 3, for example CPI = 7 states. Then you add up the numbers.
