Resumo
The paper presents a module of the device for searching the degree of optimal placement (DOPPS) for onboard computers, implementing hardware and software reorganization of the topology of the onboard computer subsystem responsible for determining the parameters of speed, altitude, and incident flow pressure under combined interference. The “early cutoff” algorithm on the Kintex-7 FPGA checks up to 1.2 · 106 routes in 0.55 μs and switches the channel in less than 0.72 μs, which satisfies the 1 μs limit established by DO-178C and ARINC 664. HIL tests showed a 15% decrease in the integral “perturbed cost” ΔL and an increase in the probability of successful transmission Ps to 0.96. At the same time, the dynamic power of the CPU decreased by 1.1 W, and the peak temperature of the crystal did not exceed 55 °C. The solution is suitable for serial implementation in UAVs and modernization of manned systems without modification of certified software.
