摘    要:本文首先定义了Java芯片系统中的地址结构对象地址、段式地址和物理地址.针对现有地址转换方法的不足,提出了一种结合段式和段页式的混合转换方法.该方法使访问对象的速度、存储空间利用率和设备复杂度等方面得到合理的折衷.文中还给出了该方法在Java芯片系统中的硬件实现方法和相关的物理存储空间分配算法,并对其进行了性能评价.

关 键 词:Java芯片  存储管理  地址转换

Abstract:Based on the analysis of memory management of JVM(Java Virtual Machine), the concepts of object address, segmented address and physical address are defined. Their relationship in Java Chip system is also presented here. After the discussion of current address translation schemes, a novel address translation technology, which hybridizes the segment scheme and segment page scheme, is presented. A perfect tradeoff will be gained among the object accessing performance, the memory utilization and the Java chip system simplicity. The hardware architecture to implement address translation and the algorithm to allocate physical memory are presented too. At the end of paper, the performance evaluation of these algorithms is given.
Keywords:Java chip  Memory management  Address translation
