Multi-Level Logic: AND-OR-Invert

F = B C' + A C' + A B

F' = A' B' + A' C + B' C

Implemented by 2-input 3-stack AOI gate

F = (A + B) (A + C') (B + C')

F' = (B' + C) (A' + C) (A' + B')

Implemented by 2-input 3-stack OAI gate

Example:

Example:

4-bit Equality Function

Z = (A0 B0 + A0' B0') (A1 B1 + A1' B1') (A2 B2 + A2' B2') (A3 B3 + A3' B3')

Each implemented in single 2x2 AOI gate
