In the upcoming Fermilab Tevatron collider run, p anti-p collisions
will occur at 132 ns intervals, and the CDF II trigger system requires that
information about drift chamber tracks be provided within 2.2 mu s of every
collision, so that tracking information can be used in conjunction with data
from other detector components to trigger on physics objects with little
background. We have developed a fast online track processor for locating
high-momentum tracks in the chamber. The design is highly parallel, and is
implemented in programmable logic devices. We describe the design of the
system and performance tests.
