The use of commercial-of-the-shelf SRAM-based FPGA devices in space applications is not yet a reality due to concerns still existing about the device reliability; therefore, more conservative approaches based on anti-fuse FPGAs are currently preferred. The major concern about the use of such devices in space stems from their sensitivity to ionizing radiation, which may alter the content of the design...
The checkpoint and rollback recovery techniques enable a system to survive failures by periodically saving a known good snapshot of the system's state, and rolling back to it in case a failure is detected. The approach is particularly interesting for developing critical systems on programmable chips that today offers multiple embedded processor cores, as well as configurable fabric that can be used...
The availability of multimillion Commercial-Off-The-Shelf (COTS) Field Programmable Gate Arrays (FPGAs) is making now possible the implementation on a single device of complex systems embedding processor cores as well as huge memories and ad-hoc hardware accelerators exploiting the programmable logic (Systems on Programmable Chip, or SoPCs). When deployed in safety- or mission-critical applications,...
The growing availability of embedded processors inside FPGAs provides unprecedented flexibility for system designers. The use of such devices for space or mission critical applications, however, is being delayed by the lack of effective low cost techniques to mitigate radiation induced errors. In this paper a non invasive approach for the implementation of fault tolerant systems based on COTS processors...
Critical applications are more and more relying on electronic components to provide the services they are designed for. The obsolescence of such electronic components has already been recognized as a critical issue that must be properly addressed. Among the different possibilities, FPGA-based emulation of obsolete digital components seems particularly interesting. This paper proposes an automatic...
