Abstract Base Class: At least a single pure virtual function is present in an Abstract class. For sub classes interface is provided by Abstract class. The instantiation of Abstract class is not possible whereas refrences and pointers could be created. Abstract class contains a pure virtual function along with normal functions and variables The purpose of Abstract class is to for up cast. So that its interface could be used by derived class. The implementation of all of pure virtual functions is necessary for all classes that inherit an Abstract class. Otherwise they would also become Abstract.

Program Plan Intro

Abstract Base Class:

At least a single pure virtual function is present in an Abstract class. For sub classes interface is provided by Abstract class.

The instantiation of Abstract class is not possible whereas refrences and pointers could be created.

Abstract class contains a pure virtual function along with normal functions and variables

The purpose of Abstract class is to for up cast. So that its interface could be used by derived class.

The implementation of all of pure virtual functions is necessary for all classes that inherit an Abstract class. Otherwise they would also become Abstract.

⚫ your circuit diagrams for your basic bricks, such as AND, OR, XOR gates and 1 bit multiplexers, ⚫ your circuit diagrams for your extended full adder, designed in Section 1 and ⚫ your circuit diagrams for your 8-bit arithmetical-logical unit, designed in Section 2. 1 An Extended Full Adder In this Section, we are going to design an extended full adder circuit (EFA). That EFA takes 6 one bit inputs: aj, bj, Cin, Tin, t₁ and to. Depending on the four possible combinations of values on t₁ and to, the EFA produces 3 one bit outputs: sj, Cout and rout. The EFA can be specified in principle by a truth table with 26 = 64 entries and 3 outputs. However, as the EFA ignores certain inputs in certain cases, it is easier to work with the following overview specification, depending only on t₁ and to in the first place: t₁ to Description 00 Output Relationship Ignored Inputs Addition Mode 2 Coutsjaj + bj + Cin, Tout= 0 Tin 0 1 Shift Left Mode Sj = Cin, Cout=bj, rout = 0 rin, aj 10 1 1 Shift Right…
