FIELD: transport.
SUBSTANCE: invention relates to aircraft avionics architecture. Proposed modular system comprises parallel processors, several cabinets arranged at different point inside aircraft and integrated into common circuit. Cabinets accommodate two main processor modules (CPM1, CPM2) and two I/O modules (IOM1, IOM2). I/O modules (IOM1, IOM2) make interfaces for systems to be controlled and are intended for intermediate data storage and control, the data coming into cabinet or being outputted therefrom. Every main processor module (CPM1, CPM2) has independent communication with every IOM module and CPM module, and several independent system programs run under control of OS in every main processor. system allows to avoid using mounting bus used in known systems.
EFFECT: higher efficiency and ease of amending applications.
