摘　　要：以某型号导弹飞行试验为研制背景,设计出一款精度高、通用性强的新型弹载计算机。该弹载计算机以高性能DSP和FPGA为系统框架,通过其丰富的外围接口和强大的处理能力,结合AD5764转换模块、MAX3490通信模块,ADUM1401四通道数字隔离器和ULN2801达林顿管驱动器组成的离散量输出等模块,解决了弹载计算机与弹上飞控部件之间复杂的并行数据处理以及多种控制算法实时解算问题,具有体积小、重量轻、精度高、实时性好等特点;经过多次飞行试验表明,该弹载计算机具有较高的可靠性和稳定性,应用前景非常广泛。Based on the development of a certain type of missile flight test, a new missile-borne computer which has high precision and high universality has been designed. The missile-borne computer with high performance DSP and FPGA as the system framework, through its rich peripheral interface and powerful processing capabilities, combined with the AD5764 conversion module, MAX3490 communication module, the discrete output module with ADUM1401 four channel digital isolator and ULN2801 Darlington tube etc, which solved the prob lem of the complex parallel date processing between the missile--borne computer and other flight control components, while solved the prob lem of real time calculation of a variety of control algorithms, also it has the advantages of small volume, light weight, high precision, good real--time characteristic and so on. The missile-borne computer has passed many flight experiments, the results show that it has high reliability and stability, while the prospect of application is very extensive.
