Detailed Description

template<unsigned int bits, LineEvent event = LINE_POS_EDGE>
class lcs::Counter< bits, event >

A class which encapsulates a counter module. This counter module increments the count on its output bus when a line event occurs on its input bus. The line event can be of any type.

Parameters:

	bits	The bit-width of the counter
	event	The event on the input bus which triggers the counter

Public Member Functions
	Counter (const Bus< bits > &output, const InputBus< 1 > &clk)
virtual	~Counter ()
virtual void	onPosEdge (int portId)
virtual void	onNegEdge (int portId)
virtual void	onStateChange (int portId)

Member Function Documentation

template<unsigned int bits, LineEvent event = LINE_POS_EDGE>

virtual void lcs::Counter< bits, event >::onNegEdge

(

int

portId

)

[inline, 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 bits, LineEvent event = LINE_POS_EDGE>

virtual void lcs::Counter< bits, event >::onPosEdge

(

int

portId

)

[inline, virtual]

A subclass of the class Module should override this function so that it can be notified of a positive edge on its input busses. If a lcs::LINE_POS_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 bits, LineEvent event = LINE_POS_EDGE>

virtual void lcs::Counter< bits, event >::onStateChange

(

int

portId

)

[inline, virtual]

A subclass of the class Module should override this function so that it can be notified of a state change on its input busses. If a lcs::LINE_STATE_CHANGE 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.
