Evolving Fault Tolerant System Based on FPGA

Abstract:

In order to overcome the single event function interrupt and SA failure, this paper proposes and implements a new way to design circuit, i.e. dynamically reconfigurable adaptive circuit design method. We load a Microblaze which is a soft CPU in FPGA as a motion control part of the circuit, as well as use some place of FPGA as evolution pool to find target circuit. Microblaze known input and the corresponding output applies genetic algorithm to search evolution pool. Depend on it, we successfully design and implement a DC Motor control system, besides, we carry out theoretical analysis on this circuit reliability and simulate circuit function repair test of SA fault, the result demonstrates that compared with the traditional circuit, this circuit and has a high reliability.
