CprE381 HW 8
. (10 points) Consider a single cycle implementation of the processor that
implements a LW, SW, R-type, BEQ, BNE, and Jump instruction. You can view the
data path in the book or notes. A stuck-at-fault is that the signal value does not change
and stuck at a value. Describe the effect that a single stuck-at-0 fault (i.e., regardless
of what it should be, the signal is always 0) would have for the signals (a) RegWrite =
0; (b) ALUop0 = 0; (c) ALUop1 = 0; (d) Branch = 0; (e) MemRead = 0; (f) MemWrite
Which instructions, if any, will not work correctly?
