摘　　要：随着电子技术的发展,实时系统对其数据总线接口的要求也越来越高。在深入研究1553B总线接口技术及协议的基础上,设计并研制了1553B总线接口SoC,该芯片自带微处理器,支持多种主机接口,可通过模式选择适配多种局部总线。同时针对所设计的SoC提出了一种通信软件的设计实现方法,该软件完成传输层和驱动层功能。通过多种测试证明该芯片完全符合MIL-STD-1553B协议,满足实时系统通信要求,具有较高的通用性、可靠性和较高的功能、性能密度。With the development of electronic technology,the requirement of reahime system data bus interface is higher than ever. Based on the research of 1553B interface technique and protocol, a SoC for implementing 1553B bus interface is designed and developed. The SoC has a microprocessor and four types host interface. With the help of program, the universal interface can be selected to different modes and is suitable for several local buses. Design scheme of SoC communication software is presented. The software realizes the function of transport layer and driver layer. The tests verified that the SoC meet the requirements of MIL- STD- 1553B protocol and reahime system communication application. The result shows that the SoC improved commonality, reliability and density of function and performance.
