Define Documentation

#define BITCOUNT

(

x

)

(((BX_(x)+(BX_(x)>>4)) & 0x0F0F0F0F) % 255)

Computes the number of bits set (1) in 32-bit argument.

See also:

BX_

#define BX_

(

x

)

Value:

((x) - (((x)>>1)&0x77777777)                    \
                             - (((x)>>2)&0x33333333)                    \
                             - (((x)>>3)&0x11111111))

Replaces each 4-bit sequence in arg by the number of bits in sequence.

See also:

BITCOUNT

Replaces each 4-bit sequence in 32-bit argument by the number of bits in that sequence (which will, of course, fit in 4 bits).

Function Documentation

int countLayerEnds

(

const unsigned int

accepts[3]

)

[static]

Counts the number of layer ends with data in the accept block.

Returns:

The number of layer ends with data in the accept block

Parameters:

accepts

The array of the 3 accept words (only 72 bits active)

static __inline int err_pad_count	(	const EBF_dirCtbDsc *	tem,
		const unsigned int **	err_ptr,
		int *	pad_cnt
	)			[static]

Calculate the size of the error contribution.

Returns:

The count, in 32-bit words, of the error contribution.

Parameters:

	tem	The TEM contribution descriptor
	err_ptr	Returned as the pointer to the error contribution
	pad_cnt	The number of 32-bit words in the pad block If negative, this is the number of 32-bit words the calculated size of the error block exceeds the actual size of the contributor. This almost always indicates the the error block is ill-formatted, making it appear as if the start of the pad block is beyond the confines of the contribution block.

Since the error count is based on the contents of the error block itself, if the error block is ill-formatted, this value can be wrong. In the one documented case, LCI failed to add the error block but still set the bit indicating the contribution had an error block. two things happened

• If a pad block was present, this pad block was misinterpretted as being the error block. Since the pad block is a block of between 0 and 3 0s, the length of the error block was calculated to be 1 32-bit word and the pad block was taken as the remaining (if any) 32-bit words. In this case the dump routine flags the error block as being bogus since no legitimate error block has an error summary word (the first word) being equal to 0.

• If the pad block is absent (i.e. the contribution ended on an even cell boundary), the error block is taken to be the next contribution header. (Note since error blocks only occur on TEMs, that there is always a next contribution header. It is either another TEM contributor or the mandatory GEM contributor.) In this case, inevitably, the calculated length of the error block is impossibly large. The returned error count is limited to say within the contribution and the pad count is set to a negative value. The negative value serves as flag to the caller that something bad has happened and the value (not terribly useful) is the number of 32-bit words that error count calculation exceeds the contribution boundary

void printData	(	const char *	name,
		const unsigned int *	dat,
		int	cnt
	)			[static]

Simple print routine.

Parameters:

	name	The contributor's name
	dat	The contributor's data
	cnt	The length of the data section in words

void QSE_dirCtbAcdPrint

(

const EBF_dirCtbDsc *

acd

)

Provides a formatted print out of the contents of the ACD contribution.

Parameters:

acd

Pointer to the ACD contributor descriptor

void QSE_dirCtbCalPrint

(

const EBF_dirCtbDsc *

tem

)

Provides a formatted print out of the contents of a CAL TEM contribution.

Parameters:

tem

Pointer to the TEM contributor descriptor containing the CAL record to be printed

void QSE_dirCtbDgnPrint

(

const EBF_dirCtbDsc *

tem

)

Provides a formatted print out of the contents of a TEM's diagnostic contribution.

Parameters:

tem

Pointer to the TEM contributor descriptor containing the diagnostic data to be printed.

void QSE_dirCtbErrPrint

(

const EBF_dirCtbDsc *

tem

)

Provides a formatted print out of the contents of a TEM's error contribution.

Parameters:

tem

Pointer to the TEM contributor descriptor containing the error data to be printed.

void QSE_dirCtbGemPrint

(

const EBF_dirCtbDsc *

gem

)

Provides a formatted print out of the contents of the GEM contribution.

Parameters:

gem

A pointer to the trigger contributor descriptor.

void QSE_dirCtbPadPrint

(

const EBF_dirCtbDsc *

tem

)

Provides a formatted print out of the contents of a TEM's pad contribution.

Parameters:

tem

Pointer to the TEM contributor descriptor containing the pad data to be printed.

void QSE_dirCtbTemPrint

(

const EBF_dirCtbDsc *

tem

)

Provides a formatted print out of the contents of a TEM contribution.

Parameters:

tem

Pointer to the TEM contributor descriptor to be printed

void QSE_dirCtbTkrPrint

(

const EBF_dirCtbDsc *

tem

)

Provides a formatted print out of the contents of a TKR TEM contribution.

Parameters:

tem

Pointer to the TEM contributor descriptor containing the TKR data to be printed

void QSE_dirPrint

(

const EBF_dir *

dir

)

Provides a formatted print out of the contributors in dir.

Parameters:

dir

The directory for this event

static int tkrLayerEndCount

(

const EBF_tkr *

tkr

)

[static]

Counts the number of layer ends with hit strips.

Returns:

The number of layer ends with hit strips

Parameters:

tkr

Pointer to the tracker data

static int tkrLenCalc	(	const EBF_tkr *	tkr,
		int	maxwrds
	)			[static]

Calculates the number of bytes, not including any padding, in the EBF_tkr record.

Returns:

The byte length of the active information in the EBF_tkr record

Parameters:

	tkr	Pointer to the tracker data
	maxwrds	The maximum number of words that can possibly be in the EBF_tkr record. This serves as a sanity check in case the serial decode of the record goes haywire.

This function must serially parse the entire TKR record for a given tower and, is, therefore, is not cheap, particularly in the case of large EBF_tkr records. If one needs both the number of layers hit, the strip count and the length of the record, it is better to use EBF_tkrLayerEndCnt and EBF_tkrStripCnt and compute the length from these values. Note that if the diagnostic block and/or the error block is present, the lengths of these blocks need to be added in.

static int tkrStripCount	(	const EBF_tkr *	tkr,
		int	layerEndCnt,
		int	maxwrds
	)			[static]

Counts the hit strips.

Returns:

The number hit strips

Parameters:

	tkr	Pointer to the tracker data
	layerEndCnt	Count of the number hit layer end ends. This is most easily acquired from EBF_tkrLayerEndCount.
	maxwrds	The maximum number of words in the TKR record. This value is currently not used, but may be used in the future as an integrity check.
