Detailed Description

Implementation to produce Compressed Data Format for the ACD contributor and the ACD portion of the GEM.

The packing of the GEM information is divided into two categories, for physics and non-physiscs event. Each starts with a set of flags

PHYSICS NONPHYSICS 0 PPS is the same as last time PPS is the same as last time 1 Conditions follow primitives Conditions follow primitives 2 No other conditions present 00 = Exception,Periodic,Solicited,Ext 3 CNO == 0 tkrThr = 0 4 calHi == 0 condsumCno = 0 5 calLo == 0 acd = 0, else use list 6 roi == 0 calHiLo == 0 7 tkr == 0

Conditions follow primitive means all the following are true If TKR 3-a-row == 0,non0 then TKR cond == 0,non0 CalHi == 0,non0,then CalHi cond == 0,non0 CalLo == 0,non0,then CalLo cond == 0,non0 CNO == 0,non0,then CNO cond == 0,non0 ROI == 0,non0,then ACD list = all 0, present TKR & ROI == 0,non0,the Thr condition =0, non0

Function Documentation

void CDF_acd_begin	(	CDF_acd *	cdf,
		CDF_acdBdy *	bdy
	)

Fills int the ACD portion of the datagram contribution used in when decoding an ACD event.

Parameters:

	cdf	The CDF_acd compress context structure
	bdy	The CDF_acdBdy structure to fill

References _CDF_acd_refs::peds, _CDF_acdBdy::peds, and _CDF_acd::refs.

int CDF_acd_construct	(	CDF_acd *	cdf,
		int	level,
		const CDF_acdCfg *	cfg,
		const LSEW_dgmFw *	dgmFw,
		void **	mem
	)

Constructs the CDF_acd compression context.

Return values:

Status

Parameters:

	cdf	The CDF_acd compress context structure to fill
	level	The maximum compression level that needs to be supported
	cfg	Target specific configuration parameter
	dgmFw	The datagram framework handle
	mem	Pointer to free memory pointer, return as the the updated pointer. If cdf is equal to the current contents of mem, then mem will be advanced by the size of CDF_acd, else this routine will believe that the only the variable allocation of cdf needs to be allocated.

int CDF_acd_sizeof	(	int	level,
		const CDF_acdCfg *	cfg
	)

Returns the size, in bytes of the GEM/ACD compression structure needed to support the specified level.

Parameters:

	level	The maximum compression level to support
	cfg	Target specific configuration

int CDF_acdCfg_construct	(	CDF_acdCfg *	cfg,
		int	level,
		void **	mem
	)

Constructs the CDF_acdCfg compression configuration.

Return values:

Status

Parameters:

	cfg	Target specific configuration
	level	The maximum compression level that needs to be supported
	mem	Pointer to free memory pointer, return as the the updated pointer. If cfg is equal to the current contents of mem, then mem will be advanced by the size of CDF_acdCfg, else this routine will believe that the only the variable allocation of cdf needs to be allocated.

int CDF_acdCfg_sizeof

(

int

level

)

Returns the size, in bytes of the ACD compression configuration needed to support the specified level.

Parameters:

level

The maximum compression level to support

static __inline unsigned int fill_acd_peds	(	ECR_acd *	aem,
		CDF_acd_pedestals *	acd,
		const ACD_DB_schema_pedestals *	peds
	)			[static]

Fills the ACD pedestals in the GEM defined order.

Parameters:

	aem	The ACD pedestals to fill in AEM order
	acd	The ACD pedestals to fill in GEM order
	peds	The ACD pedestal schema
