Title: A recongurable computing system for an autonomous sailboat
Issue Date: 2008
Abstract: This paper presents the computing infrastructureused in an autonomous unmanned smallscalesailboat. The system is build on a reconfigurableFPGA and includes custom designed interfacesfor the various sensors and actuators usedin the sailboat. The central processing unit isa 32-bit RISC microprocessor (Microblaze fromXILINX) implemented as a soft IP (IntellectualProperty) core, running at a maximum frequencyof 50 MHz. The computing system runs uClinux,a simplified version of the popular Linux operatingsystem. The usage of a reconfigurable platformenables the possibility to reconfigure completelythe processing and control hardware system.This facilitates enormously the developmentof the control system and allows the selection ofdifferent hardware control systems, according tothe navigation requirements and environmentalconditions.
