For the first time in a hadron collider, a novel trigger
processor, the Silicon Vertex Trigger (SVT), allows to select the long-lived
heavy flavor particles by cutting on the track impact parameter with a
precision similar to that of the offline reconstruction. Triggering on
displaced tracks has enriched the B-physics program by enhancing the B
yields of the lepton-based triggers and opened up full hadronic triggering
at CDF. After a first commissioning period, the SVT is fully operational,
performing very closely to its design capabilities. System performance and
first physics results based on SVT selected data samples are presented.
