高集成度飞控计算机接口模块的设计与实现
|
摘要
传统的飞控计算机接口模块一般采用DSP作为模块的主控制器进行接口数据管理。通过分析接口数据管理的工作流程,文章提出一种基于FPGA的高集成度接口模块设计方法。采用FPGA代替DSP作为主控制器、采用硬件逻辑代替接口软件进行数据管理。此方法不仅省去使用DSP时必需的外围电路从而缩减了模块重量和体积并提高了可靠性,同时硬件逻辑的稳固性和并行执行特性也极大提高了接口数据管理的可靠性和效率,实现了具有更高性能和可靠性的高集成度接口模块设计。
The DSP is usually adopted as master controller by traditional FCC IO module. This paper proposes a new designed method that will improve the density of integration of the IO module. We use FPGA as master controller to replace the DSP, and use hardware logic instead of software to manage IO data. This method reduced area and weight of the IO module through removing peripheral circuits. The robustness and concurrency of hardware logic also increases the level of reliability and efficiency of IO data management. Then we implemented the high-density IO module with high-performance and high-reliability.
