Assume that the instruction is executed in a single-cycle datapath. The Following instruction was fetched:

0000 0000 0100 1000 0110 0000 0010 0000 Assume the data memory is all zeros and that the processors registers have the following values at the beginning of the clock cycle in which the above instruction word is fetched

r0	r1	r2	r3	r4	r5	r8	r16	r12	r31
0	1	4	2	-2	15	6	8	2	-4

1) what are the values of the ALU control inputs for this instruction?

2) For each MUX, show the values of its data output during the execution of this instruction and these register classes.

3) For the ALU and the add two units, what are their data input values?

4) What are the values of all inputs for the "registers" unit?
