Abstract :
A VME-based module for use as an input to the D0 detector level 1.5 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 SRAM lookup tables for addressing integrated charge data and forming scalars, multipliers/accumulators for speed of calculation, and a single synchronous finite state machine to control all board operations
