TMS320C6701具有很好的抗辐照特性,适用于深空探测和长时间在轨飞行,在运载火箭上面级领域的飞行软件中得到广泛应用。如何通过优化TMS320C6701的加载模式、制定加载策略,提高飞行软件运行速度以满足实时性要求成为当前研究的热点和难点。本文详细介绍了TMS320C6701的引导方式,提出了基于TMS320C6701的飞行软件三级加载模式和加载策略,能最大限度的减少飞行软件运行时间,提高系统性能。实际应用验证了该方法对飞行软件设计具有一定的实用价值和借鉴意义。
TMS320C6701 has good anti-radiation characteristics, suitable for deep space exploration and long-orbit flight, in the rocket top level flight software has been widely used. How to optimize the loading mode of TMS320C6701 and make the loading strategy to improve the running speed of flight software to meet the real-time requirements has become a hot and difficult issue in current research. This article introduced the guidance mode of TMS320C6701 in detail, put forward the TMS320C6701 flight software three-stage loading mode and loading strategy, which can minimize flight software running time and improve system performance. The practical application shows that this method has certain practical value and reference significance for flight software design.
