摘　　要：在介绍实时操作系统Nucleus Plus和LTE230芯片及硬件平台的基础上,详细论述了Nucleus Plus移植过程中的系统启动、系统初始化、内存管理、中断管理、高级中断和任务管理以及操作系统的测试,指出了Nucleus Plus在LTE230芯片上移植的重点和难点。目前移植的操作系统已成功应用于LTE230通信模块中,操作系统的实时性、任务及中断管理完全满足系统需求。Based on the introduction of RTOS Nucleus Plus and LTE230 chip and its hardware platform, this paper discusses the transplanta- tion process of Nucleus Plus in system startup, system initialization, memory management, interrupt management, high level interrupt and task management and testing in detail, and presents the important and difficult points in the course of Nucleus Plus porting. Currently the porting OS has been applied to LTE230 communication module successfully, and the performances of real time, task and interrupt management of the OS can meet the full requirements of system.
