Detailed Description

A class which encapsulates a 1-bit full-adder.

Public Member Functions
	FullAdder (const Bus< 1 > &S, const Bus< 1 > Cout, const InputBus< 1 > &A, const InputBus< 1 > &B, const InputBus< 1 > &Cin)
	~FullAdder ()

Constructor & Destructor Documentation

lcs::FullAdder::FullAdder	(	const Bus< 1 > &	S,
		const Bus< 1 >	Cout,
		const InputBus< 1 > &	A,
		const InputBus< 1 > &	B,
		const InputBus< 1 > &	Cin
	)

The only meaningfull constructor for the class. A default constructor is not explicitly provided. Moreover, the one synthesized by the compiler is practically useless.

Parameters:

	S	The single line output Bus which carries the sum.
	Cout	The single line output Bus which carries the carry output.
	A	The single line InputBus object which carries one of the data lines.
	B	The single line InputBus object which carries the other data line.
	Cin	The single line InputBus object which carries the carry input to the full-adder.

Member Function Documentation

virtual void lcs::FullAdder::propogate

(

)

[virtual]

Propogates the input data line states to the output. Here, binary 1-bit addition is performed on the line states of input busses and the result is propogated to the output busses.

Reimplemented from lcs::Module.
