We examined how an instruction is executed in a single-cycle data path. problems in this question refer to a clock cycle in which the processor (single cycle processor) fetches the following instruction word: 10101100011000110100.

assume that 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:

r0 r1 r2 r3 r4 r5 r6 r8 r12 r31

0 -1 2 -3 -4 10 6 8 2 -16

a. what are the outputs of the sign-extend and the jump "shift left 2" unit (near the top of figure 4.24 from the book) for this instruction word?

b. what are the values of the alu control unit’s inputs for this instruction?

c. what is the new pc address after this instruction is executed?

d. for the alu and the two add units, what are their data input values?

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
