With the increase in quantity and scale of Static Random-Access Memory Field Programmable Gate Arrays (SRAM-based FPGAs) for aerospace application, volume FPGA configuration bit files that must be stored has increased dramatically.The use compression techniques these bitstream is emerging as a key strategy to alleviate burden on storage resources.Due severe resource constraints space-based electronics unique application environment, simplicity, efficiency robustness decompression circuitry...
To mitigate the soft-error effects for designing digital signal processing systems, a hierarchical evaluation algorithm is proposed in this paper, which used to estimate latent fault vulnerabilities based on analysis of sensitive attributes. In algorithm, evaluated scales attributes are devised vulnerability factors function modules. And then vulnerable model intervals conceived calculate confidence modules gray system. Finally, simulation results prove effective so as guide protection...
From the space and time dimension, FPGA circuit is devised some levels with "computing unit + memory/register" via analyzing characteristics of circuit. Combined location importance, connection degree among nodes their own soft error probability, an importance analysis model proposed. And then testing points are optimized based on each node using proposed model. The test results indicate that method a feasible optimization method.
Hybrid Electric Propulsion System (HEPS) is one of the ways to reduce aircraft environmental pollution. However, objective function HEPS for intelligent search design relatively simple at present. In this article, a new method solving was proposed, which solves problem poor accuracy power level modeling and improves ability explore global optimal results. This article took fixed-wing UAV that mainly performs long-range flight task as an example. The load curve methods were compared entire...
In order to address the vulnerability of embedded SRAMs single event soft errors due high-energy particles in a space radiation environment, this paper proposes novel circuit d layout design SEU tolerant SRAM based on DICE structure. A with depth 4096 and bit width 12 is completed commercial 65nm bulk silicon CMOS process, implemented using 3 layers metal, an area only 1.6 times that non-DICE SRAM. Circuit irradiation simulation results illustrate has access time less than 2.2ns upset cross...
