Consider a 4 stage pipeline processor. The number of cycles needed by the four instructions I1, I2, I3, I4 in stages S1, S2, S3, S4 is shown below:

	S1	S2	S3	S4
11	2	1	1	1
12	1	3	2	2
13	2	1	1	3
14	1	2	2	2

What is the number of cycles needed to execute the following loop? For (I = 1 to 2) {I1; I2; I3; I4;}
