面向综合模块化航电系统的驻留应用开发平台设计

摘要

The common computing resources in the Integrated Modular Avionics (IMA) system provide the hosted applications with temporal and spatial partitioning platform. The platform for applications development should comply with the ARINC 653 specification which defines the application executive interfaces for partitioning operation system. By porting and developing the Board Support Package (BSP) and AFDX network driver, for the first time, an IMA platform solution for hosted application development was achieved based on the C2K, a Commercial Off-The-Shelf (COTS) single board computer. The functionality and performance of the COTS based platform are similar to the popular common computing resources in IMA of modern civil transportation aircraft, offering a development platform for hosted applications development and debug at a pretty lower costs.%综合模块化航电系统采用时间和空间分区技术隔离不同的应用程序,驻留在分区中应用程序的开发依赖于符合ARINC 653及相关接口和通信规范的开发平台.通过移植传统操作系统的板级支持包和开发驱动程序,使得商业单板计算机C2K支持符合ARINC 653规范的VxWorks 653分区操作系统并提供AFDX网络接口,首次实现了基于商业单板计算机C2K的驻留应用开发平台,其主要功能和性能与目前主流的大型客机综合模块化航电系统相当,可用来支持驻留应用的开发和调试,大幅度降低了成本.
