摘要 对常见实时操作系统(RTOS)类型进行讨论。阐述了RTOS中实现多任务调度的基本原理,剖析了S.Ha.R.K.内核。在此基础上重点研究了反馈调度算法在该内核上的实现,给出了实现的框架结构,以及重要程序的伪代码;并对提出的两种反馈调度算法在实现方面的性能进行了评价。 The common real-time operating system （RTOS） types are discussed and the basic principle of multi-task scheduling in RTOS is described. The S. Ha. R. K. kernel is analyzed. On this basis, the implementa- tion of feedback scheduling algorithm in the kernel is focused. The frame structure and the pseudo codes are given. Two kinds of feedback scheduling algorithm in the realization of the system performance are evaluated.
