Abstract
We present a device, based on the concept of associative memory for pa ttern recognition, dedicated to on-line track finding in high-energy p hysics experiments. A large pattern bank, describing all possible trac ks, can be organized into Field Programmable Gate Arrays where all pat terns ale compared in parallel to data coming from the detector during readout. Patterns, recognized among 2(66) possible combinations, are output in a few 30 MHz clock cycles. Programmability results in a flex ible, simple architecture and it allows to keep up smoothly with techn ology improvements. (C) 1998 Elsevier Science B.V. All rights reserved .
