Figure $7\mathrm{.}22$ in the textbook defines the outputs of the control

unit, as a function of the instruction being executed. In our

classwork we extended that table with two additional rows: One

for the jr $($jump register$)$ instruction and one for the jal $($jump

and link$)$ instruction. We will now fill in the column labeled DW

for those two rows. The column labeled DW $($Data Write$)$ is the

one$-$bit signal to the Data Memory to control writing to the Data

Memory as shown in Figure $7\mathrm{.}3$ or Figure $7\mathrm{.}10.$

The DW output of the control unit for the $jr$ instruction should

be:

The DW output of the control unit for the jal instruction

should be:
