Level 1 Cal Trig Programming
13-April-2000 Philippe Laurens
COOR needs to program the following L1CT resources
Old (Run I) L1CT Resources
-
4x EM Et Reference Sets (1280 TT thresholds, TT size = .2
x .2)
-
4x HD Et Reference Sets (1280 TT)
-
4x Tot (EM+HD) Et Reference Sets (1280 TT)
-
8x Large Tile Reference Sets (40 LT of size eta x phi =
.8 x 1.6)
-
4x (max) TT Count Thresholds for EM Et Ref Set
-
4x (max) TT Count Thresholds for Tot Et Ref Set
-
Nothing for Large Tiles: Thresholds are fixed <=1, <=2,
<=3
-
4x (max) Energy Threshold on Global Missing Et
-
4x (max) Energy Threshold on Global Tot Et
-
Global EM Et and Global HD Et also available
New (Run II) L1CT Resources (list
non exhaustive)
-
Quadrant Matching And-Or Terms
-
EM and Tot Et Seed List Reference Sets for L2 Cal Pre-Processor
-
probably little to program at run time, but this area needs
more thougts
Example of Run II L1CT messages
-
"L1CT_Ref_Set EM_Et_Ref_Set 0 TT_Eta(-20:20)
TT_Phi(1:32) Value 10.0"
-
"L1CT_Count_Threshold EM_Et_Towers Ref_Set
0 Comparator 1 Value 1"
-
"L1CT_Energy_Threshold TOT_Et Comparator
0 Value 55.5"

Start working on code in about one week
