SINGLE-PROCESSOR CLASS-3 ELECTRONIC ON-BOARD DOCUMENTATION SYSTEM Russian patent published in 2015 - IPC G06F9/50 G06F21/74 

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to computer engineering. A class-3 electronic on-board documentation system comprises a single processor having at least one core; an electronic memory system communicating with the processor and holding an operating system; a network interface communicating with an on-board data network to connect to other on-board equipment including navigation systems; a display communicating with the processor; wherein the operating system executes to limit access of type-A/B applications in the electronic memory system to the electronic memory, the display and the processor; where a type-C application is design-approved to interact with the on-board data network, and the type-A/B application is not design-approved to interact with the on-board data network; where the operating system manages a separate buffer for each of at least one type-C and one type-A/B application and selects between the buffers by controlling the operating system such that the type-A/B application cannot overwrite data of the buffer for the type-C application.

EFFECT: obtaining a single-processor architecture with isolation equivalent to a multiple-processor system.
