1. L1 Tracking – Status Christian Steinle, Andreas Kugel, Reinhard Männer Computer Engineering, University of Mannheim • Contents • Motivation for different implementations • Status CBMROOT Implementation • Status FPGA Implementation • Status CELL Implementation • Status Documentation Christian Steinle, University of Mannheim, Institute of Computer Engineering

2. Motivation for different implementations • Develop a L1-Trigger with applied Hough-Transform for CBM • Implement a C++ software model in CBMROOT • Simulation of software model is too slow for CBM experiment • Implement a FPGA hardware model in HDL • Synthesis requires more ressources than single chip has • Distribute via more chips • Expensive and quite complex solution is replaced by cheap rapid prototyping system Sony Playstation III with CELL BE • Simulate FPGA chip network by using each SPU as chip • Maybe CELL BE implementation is fast enough for CBM experiment Christian Steinle, University of Mannheim, Institute of Computer Engineering
