基于BM3803处理器的即插即用星载计算机系统设计
|
摘要
针对我国星载计算机不能通用和"即插即用"的特点,文章提出一种模块化的星载计算机硬件设计方法,以某卫星原理样机为例,设计了一种基于BM3803处理器的即插即用星载计算机系统,重点研究了通用驱动软件的实现,通过软硬件结合,实现了设备模块的功能自动识别和"即插即用"功能。文章将该方案与现有星载计算机系统进行了对比分析,结果表明:该系统的处理性能更高,具有较好的通用性和扩展性,能够进行模块级替换和产品化生产,并满足新一代星载计算机系统快速组装的需求。
Most on-board computers of China are presently not in generalization and‘plug-andplay'.Taking a certain bread board on-board computer as an example,the paper designs a plugand-play on-board computer system based on the BM3803 processor,and studies the implementation of the general driver.The system accomplishes the identification of several hardware modules and the characteristic of‘plug-and-play'by combining hardware and software.Comparison and analysis of the design and that of traditional computer systems show that the system is more general and has a better performance and expansibility.Moreover,the design features the replacement between the hardware modules and realizes a commercial production,meeting requirements of the next generation spacecraft.
