Summary:This paper concerns an implementation of a fuzzy logic controller
(FLC) on a reconfigurable field-programmable gate array (FPGA) system.
In the proposed implementation method, the FLC is partitioned into many
temporally independent functional modules, and each module is
implemented individually on the FLC automatic design and implementation
system, which is an integrated development environment for performing
many subtasks such as automatic VHSIC hardware description language
description, FPGA synthesis, optimization, placement and routing, and
downloading. Each implemented module forms a downloadable hardware
object that is ready to configure the FPGA chip. Then, the FPGA chip is
consequently reconfigured with one module at a time by using the
run-time reconfiguration method. This implementation method is effective
when a single FPGA chip cannot fit the FLC due to the limited size of
its constituent cells. We test the proposed implementation method by
building the FLC for the truck backer-upper control on VCC Corporation's
EVC-1 reconfigurable FPGA board directly
