本文叙述对飞行数据进行近实时处理的嵌入系统初样的研制概况。选用国家半导体公司生产的以32016芯片为核心的双板微处理器作为目标系统,这有三方面的好处。由于在双板结构中动态随机存取存储器(DRAM)有效容量高达1兆字节,故可开发大容量应用程序。其次,它能使用标准的软件开发技术。最后,可采用为国家半导体微处理器开发的现成工具,使软件开发更为简便。 This article describes the development of embedded systems for flight data near real-time processing. Select the national semiconductor company to 32016 chip as the core of the dual-board microprocessor as the target system, which has three advantages. Due to the effective capacity of dynamic random access memory (DRAM) in a two-plate structure up to 1 megabyte, large-capacity applications can be developed. Second, it can use standard software development techniques. Finally, off-the-shelf tools developed for National Semiconductor microprocessors can be used to make software development easier.
