Reconfigurable fault tolerance: A framework for environmentally adaptive fault mitigation in space

A Novel Approach for Providing Fault Tolerance to FPGA-Based Reconfigurable Systems

“…D. Fay et al [22] talk about device level TMR accompanied with adaptive FT for the distributed memory system. The authors of [25] have proposed and demonstrated a framework for Reconfigurable Fault Tolerance (RFT) that enables FPGA-based systems to change at run-time the amount of fault tolerance being used.…”

“…This methodology allows the choice of any of the available FT techniques as per the application and environment requirements. Two very recent works have been based on this approach [25], [27]. In the case of [25], an application is run in different modes, with each mode having a different FT level.…”

“…Two very recent works have been based on this approach [25], [27]. In the case of [25], an application is run in different modes, with each mode having a different FT level. In the case of [27], the demonstrator application autonomously improves its FT features based on the current workload.…”

“…A volume of work has been done for providing FT to space applications built using SRAM-based FPGAs [19]- [22], [25]. The case of space applications is typical because here the FPGAs are exposed to high radiation environments.…”

“…Unlike [25] and [27], we intend to attach an FT level with each task comprising of the application that is being run on the FPGA. Thus, our approach combines scheduling along with the provision of FT. FPGA Scheduling is itself a very typical and wide topic that attracts the interest of a lot of researchers and various techniques are being devised and proposed for the same [28]- [32].…”
