Pipeline problem- instuction No.4 was fetched

Pipeline problem

Hi there:

In the picture attashed we see that the instuction No.4 was fetched at the 8th cycle if the brunch (IN instruction No.3) was not taken.
why the instruction No.4 did not fetshed at the 7th cycle like the case in which the brunsh is taken?

thanks for all.

I think BRANCH is being made in the time: "EX" of 3.

In cycle 7, it is decided whether to fetch the instruction if the branch is taken or not. So branch resolution takes cycles till cycle 7.
