Charged Particle Tracking in Real-Time Using a Full-Mesh Data Delivery Architecture and Associative Memory Techniques
We present a flexible and scalable approach to address the challenges of
charged particle track reconstruction in real-time event filters (Level-1
triggers) in collider physics experiments. The method described here is based
on a full-mesh architecture for data distribution and relies on the Associative
Memory approach to implement a pattern recognition algorithm that quickly
identifies and organizes hits associated to trajectories of particles
originating from particle collisions. We describe a successful implementation
of a demonstration system composed of several innovative hardware and
algorithmic elements. The implementation of a full-size system relies on the
assumption that an Associative Memory device with the sufficient pattern
density becomes available in the future, either through a dedicated ASIC or a
modern FPGA. We demonstrate excellent performance in terms of track
reconstruction efficiency, purity, momentum resolution, and processing time
measured with data from a simulated LHC-like tracking detector
