摘要
航天器软件的在轨维护能力对于维持星载软件正常运行有着极其重要的意义.随着数字信号处理器(DSP)在空间领域的广泛应用,针对DSP平台在轨维护手段的提升成为一个重要的研究问题.针对C6000 DSP平台设计了一种基于迭代链接的在轨维护方法,可实现注入代码的自动链接、段空间自动分配以及注入代码的自动提取,并进行了在轨应用验证,可有效提升基于DSP平台的航天器软件在轨维护能力,具有良好的工程应用价值.
The capacity of on-board maintenance is of great significance for the normal operation of on-board software. With the wide application of DSP in the field of Space, the improvement of on orbit maintenance methods for DSP platform has become an important research issue. A new method based on iterative link is designed, which can realize the automatic link of injection code, the automatic allocation of segment space, and the automatic extraction of injection code On C6000 DSP platform. It can effectively improve the on-board maintenance ability of spacecraft software based on DSP, and it has good engineering application value.
