Full_ADDER Class
FULL_ADDER Class implements a working full adder circuit for use in the CPU Simulator
FULL_ADDER() Constructor
FULL_ADDER myFullAdder;
| Function | Parameter(s) | Return Value |
|---|---|---|
| FULL_ADDER() | none | instantiation of newly allocated FULL_ADDER object |
FULL_ADDER() is the parameterless constructor that is responsible for creating a new instance of a FULL_ADDER circuit.
set(bool, bool, bool)
Takes 3 parameters and sets a, b, and carryI to those values. The sum is then achieved by sending a and b as inputs into an xor gate. The result of this first xor gate and the carry in are then used as input into a second xor gate. The sum is the result of the second xor gate.
Now the carry out is calculated. The carry out is achieved by first sending a and b as inputs to an xor gate. The result of the xor and the carry in are then sent, as inputs, to an and gate. a and b are also used as inputs to another and gate. The results of the two and gates are then used as inputs to an or gate, which outputs the carry out.
myFullAdder.set(true, true, true);
| Function | Parameter(s) | Return Value |
|---|---|---|
| void set() | bool, bool, bool | none |
getSum()
Returns 1 of the two outputs of the full adder, the sum.
myFullAdder.getSum();
| Function | Parameter(s) | Return Value |
|---|---|---|
| bool getSum() | none | bool |
getCarryOut
Returns 1 of the two outputs of the full adder, the carry out.
myFullAdder.getCarryOut()
| Function | Parameter(s) | Return Value |
|---|---|---|
| bool getCarryOut() | none | bool |
