Blackjack Machine - MUXADD module

Circuits that are a straight forward function of a set of inputs and outputs are often most easily expressed in equations; the adder within the MUXADD module is such a circuit. The module includes three elements: a multiplexer, the adder, and a comparator.

The multiplexer selects either the value of the newly dealt card or one of the two fixed values used for the ace (ADD10 or SUB10). The adder adds the value selected by the multiplexer to the previous score when triggered by the click signal ADDCLK. The comparator detects when an ace is present and passes this information on to the blackjack controller, BJACK.
