Carry Lookahead Adder (CLA) vs Ripple Carry Adder
Delay: 4 Gate Levels (CLA) vs 8 Levels (RCA)
Operand A (Binary)Decimal: 11
Operand B (Binary)Decimal: 7
Stage 1: Parallel Bitwise Generate & Propagate Logic (Delay: 1 Gate Level)G_i = A_i · B_i | P_i = A_i ⊕ B_i

Stage 2: Direct Carry Lookahead Generator (Delay: 2 Gate Levels - AND/OR Tree)Computed simultaneously without ripple ripple!
C1 = G0 + P0·C0Carry Out C1 = 1
C2 = G1 + P1·G0 + P1·P0·C0Carry Out C2 = 1
C3 = G2 + P2·G1 + P2·P1·G0 + P2·P1·P0·C0Carry Out C3 = 1
C4 = G3 + P3·G2 + P3·P2·G1 + P3·P2·P1·G0 + P3·P2·P1·P0·C0Final Overflow C4 = 1
