查询词典 virtual memory

This latter method of mapping the linear address space is commonly referred to as virtual memory or demand-paged virtual memory.

当内存已满，无法读入的时候，中断处理程序会根据内存的使用情况来决定把那个页置换出内存

Furthermore, in order to solve the shortage of memory capacity, paging memory management leads to the virtual memory support, in order to logically expand memory capacity.

另外，为了解决内存容量的不足问题，分页存储管理便引入了虚拟存储器的支持，以便于从逻辑上扩充内存容量。

Solution: Virtual Memory should manually specify the location and size, in principle, specify the size of virtual memory system for more than 512M is better (as the smallest and the largest space to ensure that WINDOWS does not change the location), location to see the district have extra space on the list.

解决方法：应当手动指定虚拟内存的位置和大小，原则上指定系统虚拟内存的大小为512M以上为好（最小和最大空间一样，以保证WINDOWS不会改变位置），位置看看那个分区有多余的空间就行了。

Virtual memory page replacement is an important part of virtual memory management.

页面置换算法是操作系统中虚拟存储管理的一个重要部分。

Protected mode allows for 16M of memory but is also capable of protecting the operating system and programs from accident and deliberate destruction by users, a feature that is absent in the single-user 8088/8086 Virtual memory is a way of fooling the microprocessor into thinking that it has access to an almost unlimited amount of memory by swapping data between disk storage and RAM.

在保护模式下系统可用16M的内存寻址并且可防止操作系统或程序被用户不经意或故意破坏。这个特征是单用户8088/8086所不具备的。所谓虚拟内存就是通过在磁盘存储器与RAM中交换数据将微处理器骗过，使之认为它有无限大的内存寻址空间。

Some techniques, such as multiprocessor organization, pipeline, virtual memory, ring-protection of main memory, multiple memory modules with address interleaving, cache, RAS and 1/O standard interface, have been employed in the system. A simple form of single-arm-latch has been adopted. Operating system used in HDS-9 is symmetric to each processor.

此机在系统结构上采用多重处理机结构，流水线控制技术，虚拟存储器技术，存储器环状保护技术，存储器多模交叉访问，高速缓冲技术，RAS技术，统一标准接口的I/O系统；在工艺技术方面采用高密度组装技术，用SSI-TTL电路组成单臂门闩触发器系统；在系统软件方面采用匀称或平等的操作系统来处理多重处理机关系。

To change Windows virtual memory parameters , in Windows Control Panel, double-click the System icon, click the Performance tab, click Virtual Memory, and then click Let Me Specify My Own Virtual Memory Settings.

若要更改 Windows 的虚拟内存设置，在 Windows"控制面板"中，双击"系统"图标，单击"性能"选项卡，单击"虚拟内存"，单击"用户自己指定虚拟内存设置"。

Because multiple memory locations must be accessed to resolve each virtual memory address, virtual address translation using page tables is a expensive operation.

由于分解每个虚拟内存地址都必须访问多个内存定位，用页表进行虚拟地址的转换是很繁琐的操作。

The data such as current time, memory total amount, available memory, memory swap file size, available memory swap file size, virtual memory size, available virtual memory size, last random seed and random seed provided by application program have been adopted as random number seed. Thus the problem has been solved efficiently. 2. Solve the self-security integrality problem of common data security architecture.
