对本地存储内存的访问与主存访问相比速度更快。
Local store memory accesses are extremely fast compared to main memory accesses.
主存中的每个位置都使用连续的数字地址编号，内存位置就使用这个地址来引用。
Every location in main memory is numbered with a sequential numeric address by which the memory location is referred.
对于DB2，系统主存的最大消耗者是它的缓冲池，这个缓冲池基本上是一个单独的、较大的共享内存区域。
For DB2, the largest consumer of system main memory is its buffer pool, which is basically a single, large Shared memory region.
不要忘了，这时对内存的修改需要先从L1写入l2高速缓存、然后才写入主存。
And remember that this memory modification will need to trickle down from L1 to L2 cache, and then to main memory.
SPE用直接内存访问（DMA）命令访问主存储器，可以在主存储器与称为本地库或本地存储（LS）的私有本地内存之间移动数据和指令。
The SPEs access main storage with direct memory access (DMA) commands that move data and instructions between main storage and a private local memory, called a local store or local storage (LS).
顾名思义，内存中数据库完全驻留在主存中，而不是磁盘上，这使得数据访问比传统的基于磁盘的数据块要快一个数量级。
As the name implies, an in-memory database resides entirely in main memory rather than on disk, making data access an order of magnitude faster than with conventional, disk-based databases.
但请记住它们指向在应用程序主存储内的内存(有效地址)，而非到SPE的本地存储。
However, remember that they point to memory in the main storage of the application (an effective address), not to the SPE's local store.
SPE不能直接读取主存，相反地必须通过对内存流控制器(或mfc)的单元使用dma命令来在本地存储和主存之间导入和导出数据。
The SPE cannot read main memory directly, but instead must import and export data between the local store and main memory using DMA commands to a unit called the memory flow controller, or MFC.
交换空间——虚拟内存使用磁盘空间作为对主存的扩展。
Swap-space - Virtual memory USES disk space as an extension of main memory.
PowerPC使用了加载/存储（也成为RISC）指令集，这意味着访问主存的惟一时机就是将内存加载到寄存器或将寄存器中的内容复制到内存中时。
The PowerPC uses a load/store (also called RISC) instruction set, which means that the only time it accesses main memory is for loading into registers or copying a register to memory.
Mem Usage(内存使用)：在线帮助将其称为进程的工作集(尽管很多人称之为驻留集)——当前在主存中的页面集。
Mem Usage: the online help calls this the working set of the process (although many would call it the resident set) — the set of pages currently in main memory.
计算机系统的运行不能离开主存储器，也被称为内存、主存、基本主存，及随机存储处理器(RAM)，或简单记忆体。
A computer system could not operate without main memory, also called internal memory, primary memory, primary storage, random access memory (RAM), or simply memory.
主存储器又称为随机存取存储器，简称内存。
Primary memory is known as random access memory(RAM) and simple named memory.
没有主存，一个计算机系统则无法工作，主存又可以称作是内存，基本内存，基本存储，随机存储器，或单内存。
A computer system could not operate without main memory, also called internal memory, primary memory, primary storage, random access memory(RAM), or simply memory.
在主机内部直接与CPU交换信息的存储器成为内存或主存。
In the mainframe, memory that directly transit information with CPU is referred to as internal memory or primary storage.
在主机内部直接与CPU交换信息的存储器成为内存或主存。
In the mainframe, memory that directly transit information with CPU is referred to as internal memory or primary storage.
