一种ARM+DSP架构的小型无人机飞行控制平台软件设计

Software design of ARM + DSP architecture for a small UAV flight platform

为了提高小型无人机飞控计算机的处理速度和解算精度,提出了ARM+DSP的解决方案。ARM作为主处理器负责任务管理和数据采集,DSP作为从处理器负责数据处理,两处理器通过双端口RAM进行数据交换。本设计实现了双处理器协同工作飞控软件设计,移植了嵌入式ARM-Linux系统,完成了A/D、双端口RAM等底层驱动及应用,具有可靠性高、便于维护和功能扩展的特点。

In order to improve the processing speed and calculation accuracy of small UAV flight control computer , ARM ＋DSP solution is put forward. As the main processor, ARM is responsible for the task management and data collection. DSP is responsible for data processing. Two processors exchange data through dual port RAM. This design has realized the cooperation of double CPU and flight control software, transplanted the embedded ARM-Linux system;completed the underlying drivers and application of A/D,dual port RAM and so on, with the characteristics of high reliability, easy to maintenance and function extension.
