For each of the following scenarios, list which instructions would no longer function properly if the scenario were to occur. When you list instructions, assume instructions are only of the following types: loads, stores, arithmetic, arithmetic with immediates, branches. Consider single-cycle processor only. Note that it is possible for some scenarios to stop all instructions from properly. a.) The MemRead control line is shorted to 0. (assume shorting means it will henceforth always have the value given, but the rest of the hardware will operate normally.) b.) The MemWrite control line is shorted to 0. c.) The ALUOp control line is shorted to 00. d.) The MemtoReg control line is shorted to 1. e.) The ZERO line coming out of the main ALU is shorted to 0.
