Abstract
A modular avionics system includes several cabinets arranged at various locations in an aircraft and interconnected in a network. The cabinets are used for controlling or processing signals from and to sensors, actuators and other systems of the aircraft. The system includes parallel processors, for example transputers. The cabinets comprise at least two core processor modules (CPM1, CPM2) and at least two input/output modules (IOM1, IOM2). The input/output modules (IOM1, IOM2) serve as interfaces to the systems to be controlled, and serve for the control and intermediate storage of the data flowing into and out of the cabinet. Each core processor module (CPM1, CPM2) communicates independently with each IOM module and CPM module by way of links; and in each core processor a number of independent system programs works under the control of an operating system.
