一种具有系统加速功能的机载智能IO模块设计

The Design of Airborne Intelligent IO Module for Purpose of System Acceleration

针对传统机载IO模块在工作中占用大量主处理器计算资源,且软硬件开发工作耦合度较高的问题,设计了一种机载智能IO模块。机载智能IO模块以可编程逻辑电路为控制中枢,实现完全自主的运行方式,具有状态机,状态1为周期运行模式,状态2为机内自检测模式,为每种状态设计了时间轴,并创建了基于同步串行数据总线的机载智能IO模块与主处理模块的实时信息交互机制。机载智能IO模块具有自主化、智能化、数字化的特点,可有效提升机载机电管理设备的系统运行效率,并降低机载机电管理设备的软件开发难度。

In allusion to the problem that traditional airborne IO module impropriates a great lot calculate resourse of CPU,and the problem that software development work couples deeply with hardware development work,a airborne intelligent IO module is designed.The airborne intelligent IO module is controlled by FPGA circuit,and runs independencly.The module has state machine,which one is periodic running mode,and another one is BIT mode,any of the two modes has a timer shaft.A real time information interactive mechanism based on synchronous serial data bus is established between main processing module and airborne intelligent IO module.The airborne intelligent IO module has characteristics with autonomization,intelligentization and digitization,which could highly advance running efficiency of airborneutilities management equipment.
