摘　　要：LEON3是一个可配置、可移植、高性能和开源的软核处理器,在工业领域和空间应用中得到广泛研究。论文基于LEON3软核构建了一种高性能、灵活的SoC硬件平台,并设计了UART全双工通信功能。首先介绍了LEON3开发环境硬件平台的搭建,并通过tsim-leon3模拟器,验证了LEON3 SoC的基本功能;其次研究LEON3的UART通信功能,并在LEON3 SoC硬件平台上进行了UART全双工通信实现。结果验证了基于LEON3的SoC平台的可行性,并实现了SoC的UART全双工通信功能,为SoC的开发提供一个良好的参考方案。LEON3 is a configurable, portable, high-performance and open source soft-core processor, which has been widely used in the field of industrial and space applications. In this paper, we built a high-performance, flexible SoC hardware platform based on LEON3 soft- core, and designed？the function of UART flail-duplex communication. Firstly, the build of the hardware platform of LEON3 development environment is introduced, and the basic function of LEON3 SoC is verified through tsim-leon3 simulator. Secondly, the communication of SoC UART is proposed and the UAKT fifll-duplex function is implemented on LEON3 SoC hardware platform. The experimental results show that the high-performance LEON3 SoC platform is achieved. A good reference solution for the development of SoC is provided.
