Logic Design Using Multiplexers
Design of MUXes using Divide-&-Conquer
• Saw the design of a 2:1 MUX using T-gates, as well as logic gates
• Messy and expensive to design larger MUXes using a flat TT based approach
• A 4:1 MUX can be hierarchically constructed using 2:1 MUXes
• Idea: Divide the selection problem by bits of the select/control variables
