Abstract

We present a device, based on the concept of associative memory for pattern recognition, dedicated to on-line track finding in high-energy physics experiments. A large pattern bank, describing all possible tracks, can be organized into Field Programmable Gate Arrays where all patterns 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 flexible, simple architecture and it allows to keep up smoothly with technology improvements. (C) 1998 Elsevier Science B.V. All rights reserved.
