针对无人机(UAV)飞控计算机的接口丰富、浮点运算效率高、可靠性高等要求，设计了一种基于双 TMS320F28335(简称 DSP28335)架构设计的无人机飞控计算机，一核专用于导航信息的解算和传感器信息的综合处理，另一核专用于控制律解算和机载任务管理。借助此双 CPU架构，实现了飞控计算机强大的运算与信息处理能力，以及丰富的片上资源，并且电路结构简化，CPU降额使用，系统可靠性高。该双核飞控计算机被成功应用于某微型测姿系统的组合导航信息采集处理及 Kalman滤波算法的姿态漂移校正。%Aiming at the requirements of rich interfaces, enhanced floating-point calculation and high reliability for Unmanned Aerial Vehicle(UAV) flight control computer, a kind of UAV flight control computer based on dual Digital Signal Processor(DSP) TMS320F28335(abbr. DSP28335) is proposed. The one DSP is used for comprehensive treatment of navigation and sensor information, and the other is dedicated to control law calculating and airborne mission management. Powerful computing and information processing capacity, rich on-chip resources and high reliability for its simplified circuit and CPU derating use are implemented with the dual-core design. The proposed computer has been successfully applied to the collecting and processing of navigation information and gyroscope drift compensation of Kalman filtering algorithm in a real-time Micro Electro Mechanical Systems(MEMS).
