Physical Memory Address的网络常见释义
物理内存概念 物理内存概念（Physical Memory Address） PC上有三条总线，分别是数据总线、地址总线和控制总线。32位CPU的寻址能力为4GB（2的32次方）个字节。
物理内存地址 物理内存地址（physical memory address）也用于底板之上的各种各样设备间通信（此类通信称作 内存映射(memory-mapped)I/O）。

Physical Memory Address相关例句
Although reserving chunks of the address space will not exhaust physical resources, it does prevent that memory from being used for other purposes.
虽然保留地址空间块不会耗尽物理资源，但它确实能防止内存用于其他目的。
If each address references a byte of storage, a 16-bit physical address would allow a processor to address 64kb of memory.
如果每个地址引用一个存储字节，那么一个16位物理地址将允许处理器寻址64 KB内存。
At initialization, a maximum address space is virtually reserved but not allocated to physical memory unless it is needed.
在初始化的时候，一个最大的地址空间被保留，但是仅在需要的时候才会分配物理地址。
Accessing a memory address that has been swapped is a lot slower than reading a resident (in physical memory) address because it must be loaded from the hard drive.
访问操作系统提供的内存地址要比读取(物理内存中的)常驻地址慢很多，因为必须硬盘驱动器加载它。
A DSI occurs whenever a reference is made to a virtual address that is not currently loaded in physical memory (this is a page fault).
如果对当前不在物理内存中加载的虚拟地址进行引用(这是一个页面错误)，则会出现DSI错误。
If you were writing applications to run directly on the processor without an OS, you could use all memory that the processor can address (assuming enough physical RAM is connected).
如果您编写无需操作系统，直接在处理器上运行的应用程序，您可以使用处理器可以寻址的所有内存(假设连接到了足够的物理ram)。
