The Online Silicon Vertex Tracker (SVT) is a new trigger
processor dedicated to the 2-D reconstruction of charged particle
trajectories at Level 2 of the CDF trigger. The SVT links the digitized
pulse heights found within the Silicon Vertex detector to the tracks
reconstructed in the Central Outer Tracker by the Level 1 Fast Track finder.
The SVT was recently modified in order to increase its efficiency. The new
configuration uses all the Silicon Vertex detector layers. On the other
hand the processing time has increased. This can be a problem at higher
luminosities of the Tevatron. The "Road Warrior" is a new board that
eliminates redundant track candidates before Track Fitting. It is based on
the principle of the Associative Memory. The algorithm used is described in
the paper, as well as the hardware implementation.
