Very fast rate 2-input fuzzy processor for high energy physics

The paper explains the design and the realization of a small size high-speed fuzzy processor. The processor goal is to give more 3exibility to the front-end electronics for high-energy physics experiments. The chip can be applied as a general purpose data analyzer; particularly for analyzing and reducing on-line the data coming from detectors. The application of a fuzzy processor to this +eld allows rejecting redundant data in a very short time. The design of the fuzzy processor has been done using VHDL language; it is cell-based and has been implemented with Alcatel 0:35 m CMOS VLSI technology. The chip architecture is pipelined with a clock frequency of 133 MHz; consequently the processing rate is 30 ns since only four active rules are processed. The chip size is 3 mm and the total power consumption is 200 mW with 3, 3 V of voltage supply. c © 2002 Elsevier Science B.V. All rights reserved.
