Function Documentation

void T32_LoggerData	(	int	cycletype,
		void *	address,
		unsigned long	data
	)

Add a new event to the LOGGER.

See Also

T32_FETCH T32_DATA_READ T32_DATA_WRITE T32_EXECUTE T32_LONG T32_WORD T32_BYTE

Parameters

cycletype	Type of the event, e.g. T32_FETCH or (T32_DATA_READ|T32_LONG).
address	Address of the event, in case of T32_FETCH and T32_EXECUTE its a instruction address otherwise a data address.
data	Data related to the event, needed with T32_DATA_READ and T32_EXECUTE.

Returns

void

void T32_LoggerDataFast	(	int	cycletype,
		void *	address,
		unsigned long	data
	)

Add a new event to the LOGGER without timestamp.

See Also

T32_FETCH T32_DATA_READ T32_DATA_WRITE T32_EXECUTE T32_LONG T32_WORD T32_BYTE

Parameters

cycletype	Type of the event, e.g. T32_FETCH or (T32_DATA_READ|T32_LONG).
address	Address of the event, in case of T32_FETCH and T32_EXECUTE its an instruction address otherwise a data address.
data	Data related to the event, needed with T32_DATA_READ, T32_DATA_WRITE and T32_EXECUTE.

Returns

void

void T32_LoggerInit

(

)

Initialize the LOGGER internal data structures.

This routine must be called before using any other LOGGER related routines. It initializes the logger internal data structures and calls T32_TimerInit().

Parameters

void

Returns

void

unsigned long long T32_TimerGet

(

)

Get current timestamp of architecture specific timer.

This routine is architecture specific and must be implemented by by the customer.

Parameters

none

Returns

current timestamp of the timer, 56bit width.

void T32_TimerInit

(

)

Initialize the architecture specific timer.

This routine is architecture specific and must be implemented by by the customer.

Please initialize the timer used in T32_TimerGet() in this routine which is automatically called by T32_LoggerInit().

Parameters

none

Returns

void
