【摘要】：MIL-STD-1553B是国际公认的航空总线标准，并且其应用已逐步扩展到坦克、舰船、卫星等多个领域，因此开展1553B总线的研究工作对于提升我国国防力量和科技水平具有重大意义。作为1553B的关键技术之一，1553B协议芯片的开发占据举足轻重的地位。随着系统级芯片（SoC）设计技术的发展，在一个SoC上实现对1553B总线系统的智能管理成为可能，但相关的验证难题成为SoC设计流程中的瓶颈。为了解决1553B总线相关组件快速验证的问题，，设计了具有1553B总线接口的SoC验证平台，由SoC实现1553B协议中规定的总线控制器（BC）和远程终端（RT）的功能，就可以快速的搭建1553B系统，方便地实现系统仿真验证。其中，总线控制器（BC）是总线上唯一能够执行建立和启动数据传输任务的终端，在1553B系统中起着非常重要的作用。本文针对总线控制器（BC）的功能，在深入研究1553B总线协议的基础上，设计了1553B总线接口中的总线控制器，其负责发送命令、参与数据传输、接收状态响应和监测总线系统。总线控制器配合SoC平台中的CPU实现对1553B总线系统的控制和管理。本文采用系统级语言SystemC在较高抽象层次对硬件进行建模，降低了代码转换的工作量，可以更早的进行软硬件协同验证。本文所设计的总线控制器包括3个主要的模块：AHB/1553B总线桥、1553B协议处理模块、曼彻斯特编解码模块。论文的最后对设计进行了仿真，结果满足1553B协议要求。
[Abstract]:MIL-STD-1553B is an internationally accepted aeronautical bus standard, and its application has been gradually extended to many fields, such as tanks, ships, satellites and so on. Therefore, the research work of 1553B bus is of great significance to improve the national defense strength and the level of science and technology of our country. As one of the key technologies of 1553B, the development of 1553B protocol chip occupies a pivotal position. With the development of system-level chip (SoC) design technology, it is possible to realize the intelligent management of 1553B bus system on a SoC, but the related verification problem becomes the bottleneck in the SoC design process. In order to solve the problem of fast verification of 1553B bus related components, a SoC verification platform with 1553B bus interface is designed. The 1553B bus controller (BC) and remote terminal (RT) can be quickly built by SoC. The system simulation and verification are realized conveniently. The bus controller (BC) is the only terminal on the bus that can set up and start the data transfer task. It plays a very important role in 1553B system. Based on the research of 1553B bus protocol, this paper designs the bus controller in 1553B bus interface, which is responsible for sending commands, participating in data transmission, receiving state response and monitoring bus system. The control and management of 1553B bus system are realized by bus controller and CPU in SoC platform. In this paper, the system level language SystemC is used to model the hardware at a higher level of abstraction, which reduces the workload of code conversion and can be verified by software and hardware co-verification earlier. The bus controller designed in this paper consists of three main modules: 1: AHB / 1553B bus bridge 1553B protocol processing module, Manchester codec module. Finally, the design is simulated and the results meet the requirements of 1553B protocol.
