Integrating the Electronics of the Control-Loops of the JPL/Boeing Gyroscope Within an Evolvable Hardware Architecture

This paper presents an autonomous custom reconfigurable architecture that employs evolvable hardware technology to accomplish the electronics of the control-loops of the JPL/Boeing gyroscope. The proposed adaptive hardware presents two functional modes. The switch between these two is controlled by an evolutionary strategy with only objective the most efficient adaptation of the system´s functionality. The choice of operational mode mainly depends on the density of faults that occur on the hardware. Simulation results have shown that our architecture is able to adapt the functionality of the sensor´s electronics within the presence of permanent stuck-at faults that occur on the user and configuration memory of the system. Moreover, the analysis of the power consumption reveals that the electronics that are accomplished within our reconfigurable architecture consume significantly less power compared with equivalent circuits, which are designed within industrial FPGAs
