FPGAs are promising candidates for computational tasks in space. However, they are susceptible to radiation-induced errors in their configuration memory. The recovery of configuration errors, either by device scrubbing or by module-based recovery, involves a series of reads and writes to the FPGA's configuration port, and is efficiently performed on-chip by a fast, flexible and reliable reconfiguration...
We present TLegUp, an extension of LegUp, that automatically generates Triple Modular Redundant designs for FPGAs from C programs. TLegUp is expected to improve the productivity of application designers for space, to allow designers to experiment with alternative application partitioning, voter insertion and fault-tolerant aware scheduling and binding algorithms, and to support the automatic insertion...
FPGAs are promising candidates for computational tasks in space applications. However, they are susceptible to radiation-induced errors, the most common failure being due to the corruption of their configuration memory. Module-based partial reconfiguration and frame-based scrubbing are the two most commonly used techniques for detecting and recovering from configuration memory errors. Both methods...
SRAM-based Field-Programmable Gate Arrays (FPGAs) are susceptible to radiation-induced Single Event Upsets (SEUs). Techniques for partially reconfiguring corrupted modules of Triple Modular Redundant (TMR) FPGA-based designs have been described in the literature. Most of these techniques require some form of network-on-chip for aggregating voter error messages from the system's TMR components to a...
Space processing applications deployed on SRAM-based Field Programmable Gate Arrays (FPGAs) are vulnerable to radiation-induced Single Event Upsets (SEUs). Compared with the well-known SEU mitigation solution — Triple Modular Redundancy (TMR) with configuration memory scrubbing — TMR with module-based error recovery (MER) is notably more energy efficient and responsive in repairing soft-errors in...
High-reliability SRAM-based Field Programmable Gate Array (FPGA) designs that are deployed in space are commonly triplicated to mask Single Event Upsets (SEUs) and employ either scrubbing or modular reconfiguration to recover from radiation-induced configuration memory errors. Scrubbing benefits from vendor support and clears errors anywhere in the design but suffers from longer recovery times and...
Field-Programmable Gate Arrays (FPGAs) provide ideal platforms for meeting the computational requirements of future space-based processing systems. However, FPGAs are susceptible to radiation-induced Single Event Upsets (SEUs). Techniques for dynamically reconfiguring corrupted modules of Triple Modular Redundant (TMR) components are well known. However, most of these techniques utilize resources...
