Part A: We wish to add the datapath parts and
control needed to implement the jal (jump and
link) instruction. Show the additions to the datapath and control
lines of the figure enclosed (Figure 1 below) needed to implement
these instructions in the multicycle datapath. There are multiple
solutions; choose the solution that minimizes the number of clock
cycles for the jal instruction.
