Due: Nothing to turnin, for Quiz review only.
Turnin: Nothing.
1. —(Problem 5.17 [5] <§5.5>, see the Chapter 5 exercises on the CD) This exercise is similar to Exercise 5.15, but this time consider the effect that the stuck-at-0 faults would have on the multiplexors in the multiple-cycle datapath in Figure 5.28 on page 323 (and slide 25 of 5-Processor: Datapath and Control from the lecture notes). Consider each of the following faults: RegDst = 0, MemtoReg = 0, IorD = 0, ALUSrcA = 0.
2. — (Problem 5.18 [5] <§5.5>, see the Chapter 5 exercises on the CD) This exercise is similar to Exercise 5.17, but this time consider stuck-at-1 faults (the signal is always 1).
3. — (partial) (Problem 5.29 [5] <§5.5> page 356) This exercise is similar to Exercise 5.2, but this time consider the effect that the stuck-at-0 faults would have on the multiple-cycle datapath in Figure 5.27, page 322 (and slide 25 of 5-Processor: Datapath and Control from the lecture notes). Consider each of the following faults:
a. RegWrite = 0
b. MemRead = 0
c. MemWrite = 0
d. IRWrite = 0
e. PCWrite = 0
f. PCWriteCond = 0
For parts e. and f., refer to slides 33 through 35 of the 5-Processor: Datapath and Control from the lecture notes.
4. — (partial) (Problem 5.30 [5] <§5.5> page 356) This exercise is similar to Exercise 5.29, but this time consider stuck-at-1 faults (the signal is always 1).
a. RegWrite = 1
b. MemRead = 1
c. MemWrite = 1
d. IRWrite = 1
e. PCWrite = 1
f. PCWriteCond = 1
For parts e. and f., refer to slides 33 through 35 of the 5-Processor: Datapath and Control from the lecture notes.
