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: 10001100101001111assume 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: r0r1r2r3r4r5r6r8r12r3101-24-68-10-1 2-1431a, 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? (2 points)b, what are the values of alu control unit’s inputs (aluop and instruction operation) for this instruction? (2 points)c, for the alu and the two add units, what are their data input values?
