Functions
static __inline unsigned int	prepare (unsigned int w)
	Prepares the initial word of being used in the formation of the pattern word.
static __inline unsigned int	form (unsigned int v, unsigned int hb, unsigned int ha, unsigned int pb, unsigned int pa, int bit)
	Forms the 5 bit pattern word from the bits in column left and appropriately shifts the pattern word so that it may be used directly as a byte offset into the correct statistics counters.

Function Documentation

static __inline unsigned int acd_add (  unsigned int *  buffer, unsigned int  position, const EBF_gem *  gem, const EDR_acd *  acd )  [static]

Adds the ACD record proper and the ACD portion of the GEM. Returns: The next available bit position in the output buffer Parameters: buffer  The output buffer position  The current bit offset gem  The input EBF_gem record acd  The input EDR_acd record The only error condition that this routine can deal with is PHA parity errors.

unsigned int CDF_gem_acd_compress (  CDF_vector *  bpv, const EBF_gem *  gem, const EDR_acd *  acd )

Compresses the ACD/GEM data. Parameters: bpv  Output context gem  The GEM contribution acd  The unpacked ACD contribution Returns: Size, in bits of the compressed combined ACD/GEM data

unsigned int form (  unsigned int  v, unsigned int  hb, unsigned int  ha, unsigned int  pb, unsigned int  pa, int  left )  [static]

Forms the 5 bit pattern word from the bits in column left and appropriately shifts the pattern word so that it may be used directly as a byte offset into the correct statistics counters. Returns: A word that can be used to increment the statistics pattern counter. Parameters: v  The GEM list of veto bits hb  The ACD hit bits for side b ha  The ACD hit bits for side a pb  The ACD pulse height accept bits for side b pa  The ACD pulse height accept bits for side a left  The bit number of the channel (counting from the left or MSB)

static __inline unsigned int gem_add (  unsigned int *  buffer, unsigned int  position, const EBF_gem *  gem )  [static]

Adds the GEM record. Returns: The next available bit position in the output buffer Parameters: buffer  The output buffer position  The current bit offset gem  The input EBF_gem record

static __inline unsigned int pack_adr_acd (  unsigned int *  buffer, unsigned int  position, unsigned int  adr, unsigned int  v, unsigned int  hb, unsigned int  ha, unsigned int  pb, unsigned int  pa )  [static]

Packs the ACD addressing information. Parameters: buffer  The output buffer position  The current bit offset adr  Starting address v  The GEM list of veto bits hb  The ACD hit bits for side b ha  The ACD hit bits for side a pb  The ACD pulse height accept bits for side b pa  The ACD pulse height accept bits for side a

static __inline int pack_pha_acd (  unsigned int *  buffer, int  position, const unsigned int  paccepts[2][4], const unsigned short int *  phas, int  shift, int  width )  [static]

Packs the ACD Pha values. Returns: The new bit index Parameters: buffer  The output buffer position  The bit index into the output buffer paccepts  The PHA accepts phas  The array of pha values shift  The number of bits to shift the PHA value width  The number of bits per PHA to store

unsigned int prepare (  unsigned int  w  )  [static]

Prepares the initial word of being used in the formation of the pattern word. Returns: The prepared word Parameters: w  The word to prepare On the PowerPC, 1 instruction in the accumulation loop is saved by preshifting the intial word used in the formation of the pattern word. All other platforms do the straightforward thing of shifting and oring each bit and this routine is a NOOP. By doing defining this routine, the bulk of the code is portable across platforms.
