Typedef Documentation

DFC_DB_gemV0

Typedef for struct _DFC_DB_gemV0.

There are 8 trigger primitives (CAL LO, CAL HI, 3-in-row, etc). These can be viewed as a 8-bit number. The map field member maps these 256 patterns into a 16-bit number, which is inserted into the filter's veto status word. The veto word then controls which patterns are rejected. The advantage of spreading this pattern word out to 16 classes are 2-fold

• This numbering matches the GEM's trigger engine modularity, so one can do a one-to-one mapping between a trigger engines pattern and this pattern.
• Each pattern can be prescaled at a different rate using the generic prescaling feature of the EFC facility.
