摘要
航电系统机载数据具有实时性高、数据量大、数据流快等特点。阐述了Vx Works 6.8实时操作系统下AHCI驱动设计流程,实现支持热插拔的大容量记录模块的AHCI驱动。介绍了本机载记录模块硬件组成,支持双通道共两张SATA电子盘。测试结果表明,本机载记录模块存储量大、数据传输速度快,满足现阶段航电系统机载数据记录要求,具有广泛应用价值。
Avionics system airborne data is of large amount and its data stream is fast. This paper elaborates on the design process of AHCI driver which realizes hot plug function based on VxWorks 6.8 real-time operation system; and introduces the hardware structure of this airborne record module. Test results show that this record module has large storage capacity and fast data transmission speed, which meet the requirements of avionics record system at this stage and can be widely used.
