A(n) ____________________ instruction copies data from one memory location to another.
The control signal 'ALUSrc' controls the multiplexor whose output goes into the ALU. The inputs to this multiplexor are the 'Read Data 2' from the 'Register' block and the 32-bit wide sign-extended offset from the instruction. If the instruction is a 'load word' (Iw), which of these two inputs will this control signal propagate to the multiplexor output and hence to the ALU input? Choose the best answer. Since the command is a lw, the 'Read Data 2' needs to be propagated to the ALU Since the command is a lw, the offset needs to be propagated to the ALU O This is a trick question. There is no need for the sign-extended offset to be input to the ALU as it only gets data from the registers Since this is a lw instruction, the ALU does not come into the picture at all as this datapath goes directly to the Data Memory bypassing the ALU. This is a 'dont-care' situation
Write the instruction format for the jump instruction.
(d) The table below shows the ALUcontrol signal of the datapath we discussed in class. Instruction Funct ALU Орсode ALUop ALU action operation field control Iw 00 load word XXXXXX add 0010 Sw 00 store word XXXXXX add 0010 beq 01 branch equal subtract 0110 XXXXXX R-type 10 add 100000 add 0010 R-type 10 subtract 100010 subtract 0110 R-type 10 AND 100100 AND 0000 R-type 10 OR 100101 OR 0001 R-type 10 set on less than 101010 set on less than 0111 You want to add the bne instruction into the datapath, which already includes the required hardware for the instruction. Write out the ALUop for bne and how you can determine whether the bne results in the branch to be taken.
