Detailed Description

template<int width = 1>
class lcs::Xor< width >

A template class which encapsulates a logical XOR gate. The template parameter width denotes the number of lines in the input data bus. In other words, the template parameter width denotes the number of inputs to the XOR gate. Hence, one can instantiate an N-input XOR gate by setting the template parameter value to N.

Public Member Functions
	Xor (const Bus< 1 > &output, const InputBus< width > &input)
virtual	~Xor ()
virtual void	propogate (void)

Constructor & Destructor Documentation

template<int width>

lcs::Xor< width >::Xor	(	const Bus< 1 > &	output,
		const InputBus< width > &	input
	)

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:

	output	The single line output bus of the gate.
	input	The multiline input bus to the gate.
	width	The number of lines in the input bus.

Member Function Documentation

template<int width>

void lcs::Xor< width >::propogate

(

void

)

[virtual]

Propogates the input data line states to the output. Here, an XOR operation is performed on the line states of the data lines of the input bus, and the result is propogated to the single line output bus.

Reimplemented from lcs::Module.
