Carry-Lookahead Adder 설계
캐리 신호 계산 Generate (G)와 Propagate (P) 신호:$G_i = A_i \cdot B_i$$P_i = A_i \oplus B_i$캐리 신호:$C_1 = G_0 + P_0 \cdot C_0$$C_2 = G_1 + G_0 \cdot P_1 + P_1 \cdot P_0 \cdot C_0$$C_3 = G_2 + G_1 \cdot P_2 + G_0 \cdot P_1 \cdot P_2 + P_2 \cdot P_1 \cdot P_0 \cdot C_0$$C_4 = G_3 + G_2 \cdot P_3 + G_1 \cdot P_2 \cdot P_3 + G_0 \cdot P_1 \cdot P_2 \cdot P_3 + P_3 \cdot P_2 \cdot P_1 \cdot P_0 \cdot C_0$ ..
