Histogramming in the LATOME-Firmware for the Phase-1 Upgrade of the ATLAS LAr Calorimeter Readout — •Philipp Horn, Rainer Hentges, and Arno Straessner — Institut für Kern- und Teilchenphysik, Dresden, Germany

Due to the increased luminosity and the higher effective event rate after the phase 1 upgrade the ATLAS LAr detector needs new trigger electronics. The so-called LATOME-Board was designed as a LAr Digital Processing Blade (LPDB) to reconstruct the energy deposited by the particles and is an important part of the read out system. A prototype has already been build and the firmware for the on-board FPGA is under development. The insertion of a histogram-builder in this device gives the unique opportunity to look at untriggerd data. This talk provides an insight in the LATOME-firmware and shows the different possibilities to implement the histogramm-builder.
