摘　　要：为满足军用和航天等领域高可靠串行通信的应用需求,本文通过对曼彻斯特编码、汉明码编码和数据帧冗余等技术进行研究,设计并用VHDL语言实现了高可靠串行通信控制器IP核。将该IP核集成到LEON2中进行了性能仿真和测试,结果表明该IP核较明显地提高了系统串行通信的可靠性。In order to meet the requirements of reliable serial communication in the fields of military and space application,the IP core of high-reliable communication controller is designed using VHDL,which is based on the study of the Manchester code,Hamming code and redundancy communication technologies.The IP core is simulated and tested on the platform of LEON2.The results show that the reliability of the serial communication of the system has been greatly improved.
