摘　　要：针对新一代飞行器对高精度、远射程等指标要求的不断提高,传统的直接相加的积分处理方法在TMS320C30等处理器中累计误差严重的问题,提出了一种双算子高精度积分处理方法,能够有效避免大数据和小数据相加时对齐移位带来的误差,提高积分算法精度。通过在TMS320C30处理器的工程应用表明,该算法可以在不改变硬件环境的情况下,有效提高积分算法的精度。With the development of modem information technology, missile weapon system needs to deal with a large amount of information data. In the high precision of missile weapon system, 32 bit processor, such as TMS320C30, is the bottlenecks of the high precision algorithm. The traditional integration meth- od will bring great errors. To improve the precision of integral algorithm, a double operator integral algo- rithm is presented, which can effectively reduce the shift error caused by the addition operation of big da- ta and small data. This innovative algorithm can improve the performance of weapon systems without changing the hardware conditions.
