Description

The authors present a trigger based on commercial DSP's currently being installed in the D0 experiment. The D0 trigger consists of a deadtimeless hardware phase (Level 1) which selects events for digitization, and a software phase (Level 2) using a processor farm. One of the scarcest resources in D0 triggering is the bandwidth into Level 2. Level 1.5 is an intermediate hardware trigger level designed to improve the quality of events chosen for digitization. Level 1.5 makes decisions in 10-200 μsec, but incurs deadtime while waiting for the decision
