On-orbit single event effect error rate is predicted combining accelerated radiation test and space radiation environment model for a FPGA-based signal processing platform. With partial TMR and reconfiguration mitigation method, there is no single event latch is observed when the surface linear energy transfer of heavy ion is 99.8 MeV.cm2/mg, and the error/SEU ratio is 4.7431e-004. Error rate of four...
To evaluate the total ionizing dose vulnerability of spaceborne signal processing platform, an accelerated radiation experiment is set up and on-orbit prediction method is proposed. For signal processing platform which consists of SRAM-based FPGA and DSP, function parameter and current variety are the two criterion of experiment. 60Co γ radial radiation experiment indicates that total dose is about...
Multiplier is a fundamental component for digital signal processing (DSP) applications and takes up the most part of the resource utilization, namely power and area. Approximate circuitry architectures have been studied as innovative paradigm for reducing resource utilization for DSP systems. In this paper, the 4:2 compressor based approximate multiplier architecture which uses both truncation and...
