摘　　要：针对广泛使用的微处理单元(MCU),从任务TCB设计、任务的创建和删除、任务调度的算法及实现、中断管理、优先级管理和操作系统及用户的接口等6个部分出发,提出了一个嵌入式实时多任务操作系统内核的实现方案,给出了嵌入式操作系统内核软件的功能、位置、原理和技术参数等,并给出在TOSHIBA81516位的微处理器上实现了该内核软件的应用实例,实际运行于某型号的移动掌上电脑产品中,运行情况良好。Base on MCU,an embedded real-time operating system kernel was proposed from six aspects including task TCB design, task creating, task scheduling, interrupt handling, priority level management and the interface between operating system and user.The proposed design describes the position, function, principle and technical parameter of embedded real-time operating system kernel. This kernel was runned on the platform of TOSHIBA 815 microprocessor and used in the mobile PDA products. The applications of mobile PDA products was provided to illustrate the performance of the embedded real-time operating system kernel.
