1. Repeat 4.4.2, but this time we need to support only conditional PC-relative branches.

The remaining three problems in this exercise refer to the datapath element Shift - left -2:

Repeat 4.4.2

Consider a datapath similar to the one in Figure 4.11, but for a processor that only has one type of instruction: unconditional PC-relative branch. What would the cycle time be for this datapath?

2. Which kinds of instructions require this resource?

3. For which kinds of instructions (if any) is this resource on the critical path?
