Overview
This file contains constants and structures relevant to the LATp protocol. Almost all these data structures are defined in LAT-TD-606. The driver's interest in these data structures varies from little to none.
The following is a table of the structures and the fields the driver is interested in.
LATp Data Structures
Name Description Fields of Interest

LATP_tx Transmission Statistics and Status None

LATP_rx Received Statistics and Status None

LATP_cell_hdr The 16-bit cell header The protocol field is used to dispatch data packets on the event fabric to the proper destination. The respond, destination and source fields are used when composing commands items and parsing result items, neither of which is a driver activity. The parity field is strictly the purvey of the harware

LATP_ebm_hdr The 16-bit Event Builder Module Header This is slapped on by the EBM and, other than absorbing space, the fields in the data structure are not of any interest to the driver

LATP_pckt_hdr The 32-bit combination of the 16-bit LATp cell header and the EBM header Not defined explicitly by LATP-SS-606, but is a convenience so that the driver and software can pass and manipulate the value as a coherent object

LATP_evt_summary The 32-bit summary word assembled by each hardware contributor. It is composed from the bits and pieces of the trigger message and contributor's data None. These data structure is aimed at software the decodes the event contributor

Define Documentation

#define LATP_EVT_TAG (  _evt_summary_word   ) 
 

Value:

((((_evt_summary_word) &  LATP_EVT_SUMMARY_M_TAG_HI)     \
                                       >> (LATP_EVT_SUMMARY_V_TAG_HI -    \
                                           LATP_EVT_SUMMARY_S_TAG_LO))    \
                  (((_evt_summary_word) &  LATP_EVT_SUMMARY_M_TAG_LO)     \
                                        >>  LATP_EVT_SUMMARY_V_TAG_LO))
Constructs the event tag/number from a 32-bit representation of the event summary word.

Return values:
The 17 event tag/number
Parameters:
_evt_summary_word The 32-bit representation of the event summary word.

#define LATP_EVT_TAG_LO_HI (  _tagLo,
_tagHi   )     (((_tagHi) << LATP_EVT_SUMMARY_S_TAG_LO) | (_tagLo))
 

Constructs the event tag/number from the low (least significant) bits and the high (most significant) bits of the fields found in the event summary word.

Return values:
The 17 event tag/number
Parameters:
_tagLo The low (least significant) bits of the event tag/number
_tagHi The high ( most significant) bits of the event tag/number

#define LATP_NCELLS_BYTES (  _nbytes   )     ((_nbytes + LATP_CELL_SIZE_BYTES - 1)/LATP_CELL_SIZE_BYTES)
 

Rounds _nbytes to the nearest cell size.

Warning:
This macro should not be used if _nbytes is 0, since the minimum transfer is 1 cell. However, any legitimate transfer is always at least 2 bytes in length since it must include the LATp cell header. So, in practice, this should not be a problem.

LATP_evt_summary
 

Typedef fof union _LATP_event_summary.

Overview
The event summary word is composed of bits and pieces from the original trigger message and the contributor's data. It is defined only for data packets originating from hardware acquisition modules, i.e. the AEM, GEM and TEMs.
Because it is tacked on by each contributor, the name of 'event summary' is a bit of a minomer; more properly it should be called the 'contributor summary'. However the documentation (LAT-SS-606) defines it by this name and this usage has become ingrained history, so will leave the name as is.
