Consider a pipeline processor with 4 stages S1 to S4. We want to execute the following loop:

For (i = 1; i <= 1000; i++) {I1, I2, I3, I4}

The time taken (in ns) by instructions I1 to I4 for stages S1 to S4 are given below:

S1 S2 S3 S4

I1 1 2 1 2

I2 2 1 2 1

I3 1 1 2 1

I4 2 1 2 1

The output of I1 for i = 2 will be available after
