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.
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 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.
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。

本研究中使用的数据库服务器是一个Sun X4600M2，具有八个双核处理器 (AMDOpteron 8220)和 256GB主内存。
In main, after returning from foo , namestr is actually a dangling pointer, because foo has freed that memory before returning.
在main中，当从foo返回后，namestr实际上时一个摆动的指针，因为foo已经在返回前释放了那个内存。
The SPU (a) queues a DMA PUT to transmit the contents of buffer #1 and then (b) queues a DMA GETB to execute after the PUT to refill the buffer with the next portion of data from main memory.
SPU (a) 对DMAPUT 进行排队来传输一号缓冲区的内容，然后 (b) 对 DMAGETB 进行排队，从而在 PUT之后用主内存中的下一部分数据重新填充这个缓冲区。
The other main type of processor architecture, CISC (the x86 processor being a popular CISC instruction set), allows for memory access in nearly every instruction.
另外一种主要的处理器体系结构CISC (x86处理器就是一种流行的CISC指令集)几乎允许在每条指令中进行内存访问。
Every location in main memory is numbered with a sequential numeric address by which the memory location is referred.
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。
All motherboards include a small piece of Read Only memory (ROM) which is separate from the main system memory used for loading and running software.
所有的主板都包括了一小块的只读存储器rom，它与用于载入和运行软件的主系统内存分离。
For example, a compiler may choose to optimize a loop index variable by storing it in a register, or the cache may delay flushing a new value of a variable to main memory until a more opportune time.
例如，编译器为了优化一个循环索引变量，可能会选择把它存储到一个寄存器中，或者缓存会延迟到一个更适合的时间，才把一个新的变量值存入主存。
In theory, a computer chip has two main components: a processor and a memory circuit.
理论上讲，一个计算机芯片只需要两个主要部件：处理器和存储器。
As a result, data is continually written and read from disk rather than from main memory, which is very detrimental to performance.
导致的结果是不断地从磁盘而非主内存读写数据，这是影响性能的重要限制因素。
A TLB miss requires accessing a page table that is stored in the main memory, which consumes considerably more processor cycles.
如果TLB没有命中，那么就需要访问存储在主存中的页表，而这样做需要消耗相当多的处理器周期。
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).
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。
Instead of having multiple directly accessible arguments, you get a pointer into main memory and the SPE has to issue DMA requests to get the pointed-to data from main memory.
它没有使用多个可直接访问的参数，而是使用一个指向主存的指针，SPE需要发出dma请求来从主存中获取指针所指向的数据。
The SPU queues a DMA GET to pull a portion of the problem data set from main memory to a buffer.
SPU对DMA GET进行排队，从而将涉及的数据集的一部分从主内存传输到一个缓冲区。
Queue a DMA PUT to transfer the buffer back to main memory.
对DMA PUT 进行排队，从而将缓冲区传输回主内存。
With a little care, most of the working set of a multiplayer online game can be pulled into the main memory of a large system.
只需稍加处理，多玩家在线游戏的大多数工作集就可以放在一个大系统的主内存中。
He believes SSD is a great technology to replace hard disks in very high IOPS workloads, or when data cannot go to disk and must be held by main-memory (RAM) caches.
他认为，对于IOPS非常高的工作，或者在数据不能写入磁盘，必须缓存在内存(RAM)里面的情况下，SSD是一项替换硬盘的伟大技术。
Since the SPE does not have direct access to main memory, you cannot directly dereference this as a pointer.
由于SPE不能直接访问主存，所以无法直接将其作为一个指针废弃。
Since a DB2 buffer pool is a part of the main memory of the system, the DB2 database manager allocates it for caching tables and index data when it reads or writes to and from media disks.
因为db2缓冲池是系统主内存的一部分，DB 2数据库管理器在它读取或写入磁盘介质时将它分配给缓存表和索引数据。
That's a pretty big difference because the SPE does not have direct access to main memory.
这的确是一个很大的区别，因为SPE并不直接访问主存。
