In this exercise we examine in detail how an instruction is executed in a single-cycle datapath. Problems in this exercise refer to a clock cycle in which the processor fetches the following instruction word: 10001100101001100000000000111000Assume that the data memory is all zeros and that the processor’s registers have the following values at the beginning of the cycle in which the above instruction word is fetched:R0R1R2R3R4R5R6R8R12R3101-24-64-10-12-1431a. What are the outputs of the sign-extend and the jump “Shift-Left-2” (near the top of Figure 4.24) for this instruction word?b. What are the values of ALU control unit’s inputs (ALUOp and Instruction operation) for this instruction?c. For the ALU and the two add units, what are their data input values?d. What are the values of all inputs for the “Registers” unit?

Actually, ALU is a arithmetic logic unit. Which is used to perform arithmetic and logical operations.ANSWER:- a: Sign-extend Jump’s shift-left-2a. 00000000000000000000000000010000 0001000011000000000001000000b. 00000000000000000000000000001100 0000100011000000000000110000 ANSWER:- b: ALUOp[1-0] Instruction[5-0]a. 00 010000b. 01 001100 ANSWER:- c: ALU Add (PC + 4) Add (Branch)a. 2 and 16 PC and 4 PC + 4 and 16 × 4b. –16 and –3 PC and 4 PC + 4 and 12 × 4 Answer:- d: Read Register 1 Read Register 2 Write Register Write Data RegWritea. 2 3 3 0 1b. 1 3 X (3 or 0) X 0

In this exercise we examine in detail how an instruction is executed in a single-cycle datapath. Problems in this exercise refer to a clock cycle in which the processor fetches the following instruction word: 10001100101001100000000000111000

Assume that the data memory is all zeros and that the processor’s registers have the following values at the beginning of the cycle in which the above instruction word is fetched:
