Problems solved by technology

The first is to configure a dedicated IO partition. The IO partition is responsible for network communication, and the non-I / O partition indirectly uses I / O devices through inter-partition communication with the I / O partition. This method is systemic for non-IO partitions. The overhead is large. In many cases, each partition needs IO operations, and there is a problem of mutually exclusive access to resources, and the system efficiency is low.

Embodiment Construction

[0025] In order to describe the features of the present invention more specifically, it will be described in detail in conjunction with the accompanying drawings and the following specific examples.

[0026] figure 1 A block diagram of the general system structure in which the processor module partitions communicate through the FC network is described. The processor module runs the ARINC653 operating system, which is divided into the core operating system COS and several partitions POS running on it. The core device driver of the FC end system is located in the core operating system of ARINC653, and the application program on each POS can send data to the network or receive data from the network through the FC end system.

Abstract

The present invention provides a FC network communication device and method applied between partitions of the ARINC653 operating system. The FC network communication device includes at least two processor modules, and each processor module runs the ARINC653 operating system respectively. The ARINC653 operates The system is divided into the core operating system COS and several partition POS running on it; a FC end system, the core device driver of the FC end system is located in the core operating system of ARINC653, and the application program on each partition POS can be accessed through the FC end The system sends data to or receives data from the FC network. The invention provides an FC network-based channel transmission mechanism for the ARINC653 inter-partition communication of the processor module, and realizes data exchange of application data on different module partitions based on network communication.

Description

technical field [0001] The invention belongs to the field of network communication of avionics systems, in particular to FC network communication applied to ARINC653 operating system partitions. Background technique [0002] Partitioned operating systems that meet the ARINC653 standard are widely used in integrated avionics IMA systems. The partitioning technology adopted enables one processor module to support one or more avionics application software, and ensures time and space isolation between these application software. Each application software runs independently according to the time frame. [0003] Inter-partition communication defined by the ARINC653 standard is the main way to realize information exchange between partitions, and is used to realize data exchange between two or more partitions running on the same or different processor modules. Inter-partition communication is implemented using the port and channel mechanism. The channel identifies a logical connect...
