摘　　要：为了构建基于国产芯片的星载计算机系统,研究了SPARC V8处理器在航天领域的应用,提出了一种基于国产BM3803处理器的星载计算机系统软件开发方法。根据航天控制中高可靠性、稳定性和源代码可控性的实际需要,以开源实时多处理器操作系统RTEMS为平台,开发了针对BM3803处理器的板级支持包(BSP)和设备驱动程序,并以PCI和EDAC为例,详细分析了PCI总线驱动和EDAC驱动的设计过程,最终实现了RTEMS对BM3803处理器的系统软件支持。结果表明,基于BM3803构建星载计算机系统是可行的。To build on-board computer system on the chips designed by ourselves, a method of developing on-board system software based on BM3803 is put forward for researches on spaceflight applications of SPARC V8 processors. According to the requirements of high reliability, stability and controllable source code, board support package （BSP） and device drivers are developed for BM3803 in open-source real-time multi-processor operating system RTEMS. Taken PCI and EDAC for example, the design process of PCI bus driver and EDAC driver is analyzed in details. Finally, system software supporting BM3803 in RTEMS is implemented. The results show it is available to build on-board system based on BM3803.
