基于HKS1553B芯片的总线接口模块设计与验证

Bus interface module design and validation based on the HKS1553B chip

为满足机载系统对1553B总线小型化、功耗低、重量轻、核心器件国产化的需求,设计并实现了基于HKS1553BCRT芯片的1553B总线接口模块,搭建了模块级和网络级的测试验证环境,测试验证结果表明该模块完全符合1553B总线协议,满足机载系统对1553B数据通信的需求,已在多个项目中得到成功应用,表现出了良好的可靠性和适应性,具有较高的推广应用价值用。

The BC is the core of the 1553 B bus.Once BC failure will lead to paralysis of the entire network,bu.Bus reliability engineering practice through the method set BBC.This paper presents a novel the BBC design method,the BBC at the same time working in RT mode and MT modes.The settings for the RT address x, RTx function the same as with other RT function and MT function can be selected to monitor any of the messages on the bus outside RTx.With RT or MT as compared to the traditional design of the BBC, RTMT mode as the BBC does not increase the bus load to meet the new demand,and has been successfully applied in engineering practice.
