Explain with an example how a 6 stage pipeline processor helps in speeding up the program execution as compared to non-pipelined processor.

In the following example, find out the instruction pairs which can lead to data hazard in two stage pipeline and justify your answer.

1) MOV AL, 25H

2) MOV CH, 10H

3) MOV [2002H], AL

4) INC CH

5) MOV [2004H], CH

6) ADD DX, CH
