#include "LDT/BFU.h"
#include "PBI/Endianness.h"

Classes
struct	_QDF_maps
	Maps of towers/triggers where the diagnostic data does not match the actual data. In a perfect world these would always be 0. More...
struct	_QDF_dgnCtx
	Diagnostic Block, decoding context. More...
struct	_QDF_dgnHdrEvt
	Standard header that most go on the top of the standard and pedestal event structures. More...
struct	_QDF_dgnPedEvt
	Diagnostic Block, binds together all the information used by the higher compression levels to format the diagnostic data from a pedestal event. More...
struct	_QDF_dgnCalTrg
	Structure for the decoded CAL diagnostic trigger data. More...
union	_QDF_dgnCalAcceptMatch
	Struct of the perfect accepts maps. More...

struct	_QDF_dgnTkrAccept
	Structure for the decoded TKR diagnostic accept data. More...
struct	_QDF_dgnTkrDat
	The TKR diagnostic data. This is really more for symmetry, paralleling the QDF_dgnCalDat structure. More...
struct	_QDF_dgnDat
	The diagnostic data, binding together the CAL and TKR diagnostic data. More...
struct	_QDF_dgnStdEvt
	Diagnostic Block, binds together all the information used by the higher compression levels to format the diagnostic data from a standard event. More...
struct	_QDF_dgnEvt
	Intermediate format to hold the diagnostic data while it is being decoded. More...

Typedef Documentation

QDF_dgnCalAccept

Typedef for struct _QDF_dgnCalAccept.

This structure contains a bit map of which towers have diagnostic blocks that do not match that predicted by the data and for each such tower, an array of 8 words giving the non-matching data.

QDF_dgnCalTrg

Typedef for struct _QDF_dgnCalTrg.

This structure contains a bit map of which towers have diagnostic blocks that do not match that predicted by the data and for each such tower, an array of 8 words giving the non-matching data.

QDF_dgnTkrAccept

Typedef for struct _QDF_dgnTkrAccept.

This structure contains a bit map of which towers have diagnostic blocks that do not match that predicted by the data and for each such tower, an array of 4 words giving the non-matching data.

Function Documentation

QDF_dgn_gen_cal_trg_decode	(	QDF_dgnCalTrg *	trg,
		unsigned int	calHiLo,
		unsigned int const *	src,
		unsigned int	max,
		BFU	bfu
	)

Decodes the CAL trigger bits portion of the diagnostic data.

Returns:

The updated BFU (current word being decoded and the current bit position).

Parameters:

	trg	The diagnostic CAL trigger structure to hold the decoded data.
	calHiLo	The map of towers that have encoded trigger bits
	src	The input bit stream to be decoded
	max	The maximum number of bits in the bit stream
	bfu	The value of the current 32-bit word being decoded and the current bit position.

BFU QDF_dgn_gen_hdr_decode	(	QDF_maps *	dmaps,
		unsigned int const *	src,
		unsigned int	max,
		BFU	bfu
	)

Decodes two difference maps

• The map of CAL/TKR towers whose diagnostic accept data differ from that predicted by the data.
• The map of CAL towers whose CAL LO and/or CAL HI trigger bits differ from the GEM CAL LO and CAL HI mask trigger summary word.

Returns:

The updated BFU (current word being decoded and the current bit position).

Parameters:

	dmaps	Returned with the values of the two maps
	src	The input bit stream to be decoded
	max	The maximum number of bits in the bit stream
	bfu	The value of the current 32-bit word being decoded and the current bit position.

BFU QDF_dgn_gen_tkr_accept_decode	(	QDF_dgnTkrAccept *	accept,
		unsigned int	map,
		unsigned int	err_map,
		QDF_tkrEvt const *	tkr,
		unsigned int const *	src,
		unsigned int	max,
		BFU	bfu
	)

Decodes the TKR accept bits portion of the diagnostic data.

Returns:

The updated BFU (current word being decoded and the current bit position).

Parameters:

	accept	Array of the 72 accept bits for each tower
	map	The map of towers that have encoded accept bits.
	err_map	The map of towers that have tracker readout errors.
	tkr	The TKR data. The encoded data are the exceptions and must be XOR'ed with the TKR accept bits found in the data to produce the TKR diagnostic accept bits.
	src	The input bit stream to be decoded
	max	The maximum number of bits in the bit stream
	bfu	The value of the current 32-bit word being decoded and the current bit position.
