The article deals with the methods for providing information and functional security of airborne navigation and landing equipment for special (military) purposes based on machine-to-machine direct access to memory, as well as hardware reconfiguration of the system structure in case of failure.
The analysis of the organization of information exchange between computational modules in real-time systems based on RDMA Consortium technology, high-speed SRIO interface and machine-to-machine direct memory access has been carried out.
It is shown that, in accordance with the principle of import substitution, the most effective way for the organization of high-speed information exchange in computing systems is to use the domestic method of organizing data exchange - a machine-to-machine direct memory access that implements conveyor data transfer compared to the RDMA Consortium technology, and the SRIO interface developed by Texas Instruments, Freescale, Semiconductor and others.
The comparative analysis of the temporal characteristics of the restoration of the computational process after a failure, in real-time systems based on the RapidIO- SRIO serial interface and based on the interface of the machine-to-machine direct memory access is carried out.
It is shown that, in accordance with the principle of import substitution, the most effective means to reduce the recovery time of the computational process after a failure in real-time systems compared to the SRIO interface applied by foreign companies is using of the domestic method of organizing data exchange - a machine-to-machine direct memory access realizing conveyor data transfer.
The results of a comparative analysis of the use of hardware and software for organizing the restoration of the performance of airborne navigation and landing equipment after a failure by means of the structure reconfiguration are presented. It is demonstrated that the use of hardware control and management of the reconfiguration of the structure in combination with the machine-to-machine communication manual allows to increase the efficiency of ensuring information and functional security of airborne navigation and landing equipment for special (military) purposes.
