摘要： 针对硬实时环境的特点，提出了一种新的利用任务截止期来管理缓冲区的方法，前提是该环境下使用最早截止期优先的任务调度算法。该截止期缓冲区管理方法的主要特点是：在保证周期任务的缓冲区可用的同时，有效利用缓冲区资源，得到最佳的非周期实时任务缓冲区请求响应。详细讨论了该方法及其实现。

Abstract: This paper presents a new approach of buffer management using task deadline under hard real-time circumstance, with the premise of earliest deadline first task scheduling scheme. The approach aims at gaining optimal response of buffer requests from aperiodic tasks, while guaranteeing the availability of periodic tasks' buffers . This paper discusses the approach and its implementation in detail.
