Description
The global feature extractor (gFEX) is a component of the Level-1
Calorimeter trigger Phase-I upgrade for the ATLAS experiment. It is
intended to identify patterns of energy associated with the hadronic
decays of high momentum Higgs, W, & Z bosons, topquarks, and exotic
particles in real time at the LHC crossing rate. The single processor
board will be implemented as a fast reconfigurable processor based on
four largeFPGAs. The board will receive coarse-granularity information
from all the ATLAS calorimeters on 264 optical fibers with the data
transferred at the 40 MHz LHC clock frequency. The gFEX will be
controlled by a single system-on-chip processor, ZYNQ, that will be
used to configure FPGAs, monitor board health, and interface to
externalsignals. Although the board is being designed specifically for
the ATLAS experiment, itis sufficiently generic that it could be used
for fast data processing at other HEP or NP experiments. We will
present the design of the gFEX board and discuss how it is
beingimplemented.
