摘　　要：用垃圾收集器进行动态内存管理对大规模软件系统的开发具有重要意义,为把垃圾收集器应用到嵌入式实时系统中,对垃圾收集器实时化进行了研究,提出了动态执行垃圾收集器任务以及用最短时限优先(EDF)算法调度垃圾收集器的算法,仿真实验和内存分析表明,与以往的实时垃圾收集器相比,所提出的算法可以进一步降低系统内存需求,提高系统的灵活性,并对分布式垃圾收集器进行了研究,性能分析表明基于关键引用验证的分布式垃圾收集器更适用于大规模分布式系统.Dynamic memory management with garbage collection is very important for development of large-scale software system. To apply garbage collection into embedded real-time system, real-time garbage collection is researched in this paper. Dynamic execution of garbage collection and scheduling garbage collection by EDF are proposed. Memory analysis and simulation results show that prpposed algorithms can reduce memory requirement and enhance flexibility of system compared with previous work. Distributed garbage collection is also researched and performance analysis shows that proposed distributed garbage collection based on critical reference verification fits for large-scale distributed system.
