What are the values of control signals generated by the control in Figure 4.17 for instruction a &b? 2 Which resources (blocks) perform a useful function for this instruction? .3 Which resources (blocks) produce outputs, but their outputs are not used for instruction a & b? Which esources produce no outputs for instruction a & b? In this exercise, we examine how resource hazards, control hazards, and ISA design can affeet pipelined
