10. How many operations can the MIPS register file perform per clock cycle?
a. One: either a read, or a write.
C.
b. Two: one read and one write.
Three: one read and two writes.
d. Four: two reads and two writes.
e. Three: two reads and one write.
11. In a state diagram (circles and arcs), the circles represent:
a. Inputs.
b. Outputs.
C. States.
d. Clock signals.
e.
The D outputs of the latches.
12. What is an LED?

c. A Less-than or Equal Dectector.
d. A Left-End Divider.
e. A Limited Event Doubler.
13. Why does lw use rt as the destination register instead of rd?
a. This question is bogus: Iw does use rd as the destination register.
b. This question is bogus: lw doesn't have a destination register.
c. This question is bogus: there is no lw instruction.
d. Because lw is an I-Format instruction and there is no rd field in I-Format instructions.
e.
Because rd is used for shifting in lw instructions.
14. How are Finite State Machine state transitions indicated on a state diagram?
a. By circles.
b. By arcs connecting circles.
c. By a symbol above the horizontal line inside the circles.
d. By symbols below the horizontal line inside the circles.
e. By the letters S.T. or s.t. next to the circles.
15. What comes out of Read data 1 in the Register File?
a. The rd field of the instruction.
b. The rt field of the instruction.
c. The rs field of the instruction.
d. Register[rt]
