基于确定周期性任务的进程管理及可调度性分析

文中讨论了基于确定周期性任务的实时进程管理，对确定周期性任务采用调度器生成的管理方式，通过截止期递增分类法将非性任务分为两类，分别采用中断内抢占调度和信号调度，提出了改进的最大紧急度优先算法，分析了目标系统的可调度性，给出了春可调度的充要条件。

STUDY OF DETERMINATE-PERIODIC-TASK-BASED PROCESS MANAGEMENT AND ITS SCHEDULABILITY

In this paper, determinate-periodic-task-bas process management for real-time system is studied. A scheduler generating method is developed to manage determinate periodic tasks. Nonperiodic tasks are divided into two classes by the deadline increasing method. The two classes of tasks are managed by interrupt scheduling and signal scheduling. An enhanced maximum urgency first algorithm is also developed for scheduling. the schedulability of the target system, is also studied and the necessary and sufficient condition for the feasibility of the target task set is given.
