Description
Consider the pipeline when the 100 ADD instruction is in the WB stage, the 104 LDUR instruction is in the MEM stage, the 108 CBZ instruction is in the EX stage, and the 112 ADD instruction is in the ID stage. In the figure below, label all of the control signals (including both those coming directly out of the control unit and those coming out of the pipeline registers) with their appropriate values, using don’t cares where appropriate. In this figure, the instructions have been drawn above the appropriate set of pipeline registers. We have also filled in the solution for the WB stage, and given the names of the control signals whose values you need to determine for the other three stages.
