** Data hazards 1
At some cycle the following instructions can be found in a 5 stage design:
#+begin_src text
EX: || MEM: || WB:

memWrite = false || memWrite = false || memWrite = false

For the operation currently in EX, from where (ID, MEM or WB) should the forwarder get data from for rs1 and rs2?

Should the forwarding unit issue a load hazard signal?
(Hint: what are the semantics of the instruction currently in EX stage?)

* Question 3 - Benchmarking
In order to gauge the performance increase from adding branch predictors it is necessary to do some testing.
