基于DSP+FPGA的导航制导一体化计算机设计

Design of Integrative GNC Computer Based on DSP+FPGA

对于目前小型化导弹的发展趋势,文章设计了一种以DSP为核心算法处理芯片,FPGA为外围输入输出接口,可实现MEMS惯性导航与惯性、半主动激光制导,可进行PWM输出控制舵机的一体化计算机;文章对硬件设计给出了总体和分模块的详细描述,给出了软件设计的流程框图;设计实现了导航功能与制导功能的系统一体化与结构小型化,输入输出接口丰富;经过试验调试验证了其技术可行性。

With the development of miniature missile, this article designed a integrative computer based on DSP processor as algorithm operating chip and a FPGA as peripheral interface for input/output, which can achieve strap--down inertial guidance based on MEMS and semi active laser guidance, It can also control electro mechanical actuator by PWM; this article gives an explicit description of hardware in collectivity and in modules and software flow chart; this design realize a integrative and small system for navigation, guidance and control. It has plentiful interface and it was testified that the system is applicable.
