40. The brighten control located in the data routing and multiplexing circuitry then accesses the current contrast word to be intensified whenever signal HE is high and Table A is being displayed. Again referring to FIG. 39, there is shown a multiplexer 3940 and a four-bit adder 3930. ...
seventh bit output of the shift register 36 are applied to a voter circuit 48. Thus, the voter circuit 48 determines the binary value of each bit in each group of three equally spaced bits, and produces a binary value representing the majority binary value of those bits. For example, if ...

A 4-2 carry-save adder, for the purposes of this description, is an adder that receives four one-bit binary data inputs and a one-bit carry input, all of the same weight and, in response to these five inputs, generates a one-bit binary data output of the same weight as the data...

Thus, we can simplify the logic function of the 1-bit full adder, 4-bit adder, and 4-2 compressor so that we can further reduce the critical path delay and the number of transistors. For example, the truth table of simplified full adder is given in Table 3. Table 3. Truth table of...
