This paper presents an effective design space exploration strategy for the development of dependable systems using selective hardening techniques based on software. Instead of design space exploration approaches based on brute-force or time-consuming fault injection experiments, this strategy is grounded in an early estimation of the register file criticality in microprocessor-based systems. This...
This paper proposes a method for tuning compilations to improve the size, execution time and reliability of the final application altogether. Our approach implements a genetic strategy with a multi-objective evolution that takes advantage of the NSGA-II algorithm for selecting the best compilations. Experiments show that reliability can be improved by efficiently exploring the compiler optimization...
This paper analyses the nature of fault tolerance software-based techniques and the influence of their overheads to determine an efficient strategy for applying those techniques in a selective way. Several considerations that have to be taken into account are presented in this work. These include an analysis of fault coverage and overheads when selective hardening is adopted; side effects of selective...
