引用计数垃圾收集器通常具有增量式和实时性特征，但存在垃圾收集器中断执行程序时间较长的情况。本文实现了一个并发引用计数垃圾收集器，使得垃圾收集器和工作程序并发执行，避免了垃圾收集器中断执行程序。基于 C ++的语法标准和应用编程接口，无需修改编译器和存储分配器，且收集器和工作程序的同步是锁免除的。 Linux 操作系统中的实现和实验表明，收集器有极低(低于0.2%)的处理器损失。

Reference-counting garbage collector has incremental nature of most of its operation and can easily satisfy real-time requirements. However, there are cases in which garbage collection interruptions can be long. This paper implements a concurrent reference-counting garbage collector for C + + , which can avoid the cases where collector interrupts mutators. The implementation is based on C + + grammar standards and application programming interfaces, so it is no need to modify compiler and memory al-locator. The cooperation between collector and mutator is lock-free. The implementation and experiments in Linux OS show that the CPU cost is extreme low(less than 0. 2% ).
