Abstract

The silicon vertex trigger (SVT) processor has been built at CDF for extremely fast (~10 musec) and high precision (roughly offline quality) pattern recognition. It is going to be upgraded to have at high luminosity the same crucial role it had in the data collection for the RUN II physics. A modern version of most of the SVT boards is obtained with a minimum of new hardware. A pulsar board, which was designed for and is now being used in the CDF level-2 upgrade, has been used for most the SVT functions that needed to be upgraded. The pulsar combines the power of dedicated hardware with the flexibility of general purpose CPUs. The new sequencer (AMS) that controls the associative memory (AM) operation for pattern recognition, uses a small fraction of a pulsar board. The same pulsar is powerful enough to also carry out the road warrior function (AMS-RW), to remove redundant track candidates prior to track fitting. We report about the AMS-RW design, tests and performances
