16:1 MUX

The 16:1 MUX is constructed from five MX21S macros, each a 4:1 MUX with two selects. This is the largest multiplexor in the first release. Four of these will feed into the fifth to form the 16:1 MUX structure. Since there are two 16:1 MUXs, there will be 10 MX21S macros required. An 8:1 or 16:1 MUX MSI macro would simplify the design. The basic design is shown in Figure A-7.
