| 摘 要： | 将Java成功地移植到嵌入式系统的关键是虚拟机(JVM)技术.Java虚拟机是一种软件,对Java程序而言,它表现为具有单一硬件和操作系统特性的软件“计算机”,它能够使采用Java编程语言编写的程序无需修改就可以运行在大多数操作系统和硬件平台上.JVM具有自动内存回收功能,但是在嵌入式系统中,却不能采用传统的内存回收算法,因为这样的算法不能有效消除Java程序中的内存泄漏,从而会影响嵌入式系统的稳定性.本文分析了产生这种内存泄漏的原因,并提出了一种适应于嵌入式系统的JVM内存回收机制.

| Abstract: | Java virtual machine is the most important technology to plant Java into embedded system, which is some kind of software. As far as programs are concerned, it is like a software - computer that owns some properties of hardware and operation systems. Through Java virtual machine, Java programs can run on most of platforms of hardware and operation systems without being changed. Java virtual machine has a function called auto memory collection. But in embedded systems, the traditional mechanism of auto memory collection is not practical because it can not prevent memory leaks that might cause bad effects on reliability of embedded systems. In this paper, the reason of memory leaks is introduced, and a mechanism of auto memory collection for embedded systems is recommended. |
