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。
For example, there are no addressing exceptions since all Pointers get aligned and truncated to the local store size when attempting a memory access.
例如，根本就不存在寻址异常，因为所有的指针都是对齐的，并且在视图访问某处内存时都根据本地存储的大小进行了截断。
The user space memory access functions to be explored are listed in Table 1.
用户空间内存访问函数在表1中列出。
On the other side are the technological advances made in the platform, including architectures (multiprocessing, symmetric multithreading, non-uniform memory access [NUMA]) and virtualization.
另一方面，它要考虑平台方面的技术进步，包括架构（多处理、对称多线程、非一致内存访问 [NUMA] 和虚拟化）。
Some types of memory access errors (like using a NULL pointer) cause a program to crash outright.
有些类型的内存访问错误 (比如使用一个NULL指示器) 将会导致一个程序完全崩溃。
Therefore, the amount of time required for any particular memory access is completely unknown (if the memory is swapped out, who knows how long it will take).
因而，某一内存访问所需的时间是完全未知的(如果内存被换出，所需时间的长短是不可知的)。
At that point, pulling data may involve some kind of redirected memory access as opposed to actually binding to a database and initiating a transaction.
到那时，pull数据可能需要某种重定向的内存访问，而不是真正绑定到数据库，然后开始一个事务。
Because workloads with high Symmetrix cache read-hit rates are serviced at memory access speed, storing the data needed on EFDs may not result in a significant increase in performance.
因为具有高symmetrix缓存读中率的工作负载都是以内存访问速度实现的，所以在EFD中存储所需要的数据可能不会对性能有大的改进。
Purify adds value to your existing correctness tests by simultaneously checking for memory access errors.
Purify 可以通过同时检查内存访问错误来对您的现存正确性测试增加价值。
To enable memory access, it provides put and set methods for ints, chars, and bytes.
为允许内存访问，它为int、char和byte提供了put 和set方法。
Your write system call will be interrupted by the bus error signal SIGBUS, because you performed a bad memory access.
此时write系统调用会被进程接收到的SIGBUS信号中断，因为当前进程访问了非法内存地址。
The register indirect addressing mode uses a register to specify the whole address for the memory access. This is used for numerous situations, including, but not limited to
寄存器间接寻址模式使用一个寄存器来指定内存访问的整个地址。
The first copy (see Figure 1) is performed by the direct memory access (DMA) engine, which reads file contents from the disk and stores them into a kernel address space buffer.
直接内存存取(direct memory access,DMA)引擎执行了第一次拷贝(参见图1)，它从磁盘中读取文件内容，然后将它们存储到一个内核地址空间缓存区中。
On C or C++ projects, we always made it mandatory to run Purify on components to prevent memory access violations from making their way into production code.
在C或者 C++项目中，我们已经强制在组件上运行Purify来预防进入产品代码的内存访问的违规。
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。
CICS TG on z/OS makes use of the EXCI to provide high speed cross memory access to CICS, a mechanism not available on other platforms as it is an MRO-based communications mechanism.
z/OS上的CICSTG使用EXCI提供对 CICS 的高速交叉存储访问，这是其他平台无法提供的机制，因为它是基于MRO 的通信机制。
Any memory access that is not available by other modes (the address can be calculated by other means and stored in the register, which is then used for the access).
使用其他模式无法进行的内存访问(地址可以通过其他方式进行计算，并存储到寄存器中，然后就使用这个值来访问内存)。
The main purpose for large page usage is to improve system performance for high-performance computing applications or any memory-access-intensive application that uses large amounts of virtual memory.
使用大页面的主要目的是，提高高性能计算应用程序或使用大量虚拟内存的任何内存访问密集型应用程序的系统性能。
直接内存访问。
Even though time needed for one memory access is quintupled, caching permits performance to remain reasonable.
尽管每次内存存取的时间是很大的，高速缓存使执行的时间还是可以接受的。
Non-uniform Memory Access (NUMA) was introduced in the 2.6 kernel for Linux on POWER, and this feature is further optimized in the latest releases of RHEL5 and SLES10.
Non - uniformMemory Access (NUMA)是针对Linux onPOWER在2.6内核中引入的，这个特性在RHEL5和SLES10的最新版本中得到进一步优化。
