基于RMA的雷达数据处理任务可调度性判定

Analyzing the schedulability test of radar data processing task based on RMA

实时系统中任务的可调度性是系统正确的关键.单调速率调度算法RMA是任务调度的重要算法,通过对雷达数据处理任务的时间需求模型的分析,使用RMA对该任务进行了可调度性判定.在分析任务两种不同的实现方法及相应时间开销的基础上,给出了这两种实现方法在RMA下可调度性判定的充分必要条件.

The schedulability of task in a real-time system is a key factor. RMA is an important algorithm of real-time task scheduling. Based on the time requirements model of Radar Data Processing task, the RMA- schedulability of the task is analyzed. By the time overhead of the task, this paper proposed the necessary and sufficient conditions of the task for RMA-schedulability.
