Abstract :
A VME-based module for use as an input to the D0 detector level 1.5 trigger is described. Its main function will be the confirmation of electron candidates flagged by the first level calorimeter trigger using digitized data from the transition radiation detector (TRD). Features of the board include the use of fast FIFOs to store incoming track coordinates, dual ported static random-access memory (SCRAM) lookup tables for addressing integrated charge data and forming scalars, multiplier/accumulators for speed of calculation, and a single synchronous finite state machine to control all board operations.<>
