Suppose 8 bit registers have following contents X=00001111 Y=10101010 Z= 11011011 W=00110011 What will be the 8 bit values of each register after execution of following sequences of microoperations ? X ← 𝑋 + 𝑌 Z←Z⋀ 𝑊, 𝑌 ← 𝑌 + 1 X←X-Z
Notably, the inclusive NOR (Not-OR) gate gives an output which is normally at logic level “1” and only goes “LOW” to logic level “0” when ANY of its inputs are at logic level “1”. The Logic NOR Gate is the reverse or “Complementary” form of the inclusive OR gate.
Also we know that If both A and B are NOT true, then Q is true” from a general perspective which in this case is defined as:
f k (0, 0) = fk (0, 1) = fk (1, 1) = 1; fk (1, 0) = 0
For the NOR gate,
Thus we obtain have
We can derive a truth table that looks like this:
