Detailed Description

template<unsigned int factor, unsigned int delay = 0>
class lcs::FrequencyDivider< factor, delay >

A module which divides the frequency of the input signal by a specified factor. The factor is specified by the first template parameter. The second template parameter specifies the input to output propogation delay.

Public Member Functions
	FrequencyDivider (const Bus< 1 > &output, const InputBus< 1 > &input)
virtual	~FrequencyDivider ()
virtual void	onPosEdge (int portId)
virtual void	onNegEdge (int portId)

Constructor & Destructor Documentation

template<unsigned int factor, unsigned int delay>

lcs::FrequencyDivider< factor, delay >::FrequencyDivider	(	const Bus< 1 > &	output,
		const InputBus< 1 > &	input
	)

The only usefull constructor for the class. The default constructor, if synthesised by the compiler, is practically useless.

Parameters:

	output	The bus of the module.
	input	The input bus of the module.

template<unsigned int factor, unsigned int delay = 0>

virtual lcs::FrequencyDivider< factor, delay >::~FrequencyDivider

[inline, virtual]

Member Function Documentation

template<unsigned int factor, unsigned int delay>

void lcs::FrequencyDivider< factor, delay >::onNegEdge

(

int

portId

)

[virtual]

A subclass of the class Module should override this function so that it can be notified of a negetive edge on its input busses. If a lcs::LINE_NEG_EDGE event occurs on an input bus, the bus will call this function on the corresponding module object as a notification of the occurance of the event.

Reimplemented from lcs::Module.

template<unsigned int factor, unsigned int delay>

void lcs::FrequencyDivider< factor, delay >::onPosEdge

(

int

portId

)

[virtual]

Function which toggles the output line state at the suitable positive edge. A user of libLCS will never need to use this function directly/explicitly.

Reimplemented from lcs::Module.
