THE DØ CENTRAL TRACKER TRIGGER

The goals of high energy physicists for the next decade require new designs for the online systems of collider experiments. We describe the new DØ Central Tracker Trigger (CTT) System, which makes heavy use of field programmable gate arrays (FPGA) and digital signal processors (DSP) to allow the system to cope with the greatly increased data rate anticipated at the Fermilab Tevatron. We describe briefly how the CTT system meets the physics goals of the collaboration.
