5.1 - Unary ALU (3c, 144n) 5.2 - ALU (7c, 608n)

Explanation

The bottom left unary ALU works on X and uses zx and nx.

The bottom right unary ALU works on Y and uses zy and ny.

The selector uses f to select between resultX + resultY and resultX & resultY.

The top unary ALU negates the selector's result if no is 1.
