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。

If you do, the value of the counter must first be copied on to a register, decremented, and then updated to its memory. 如果这样做,counter的值必须先复制到寄存器,递减,然后对其内存更新。
The index register is added to the specified address, and the result is used as the address for the memory access. 索引寄存器会与某个指定的地址相加,结果用作访问内存时使用的地址。
Whenever memory is accessed in real mode, the physical processor adds the value of the RMO register to the partition's specific real address so that it references a true address in the physical memory. 在采用实模式访问内存时,物理处理器会将RMO寄存器的值与分区特定的实地址相加,以使得它能够引用物理内存中的实地址。
In register mode, rather than accessing the contents of main memory, you access registers. 在寄存器寻址模式中,我们也不会访问主存的内容,而是访问寄存器。
General register unit The fastest memory is known as cache memory and is what it sounds like-memory that is used to temporarily hold, or cache, contents of the main memory. 通用寄存器单元-用以存储微程序的暂时存储区最快的的存储器是高速缓存,它被用来暂存主存中的内容。
Local storge address register addressable memory 局部存储器的地址寄存器
The CLR JIT can only track a fixed number of variables for register allocation; once it has to track more than this, it begins to spill the contents of registers into memory. CLRJIT只能跟踪固定数目的寄存器分配变量;一旦需要跟踪的数目超出这个数目,它就开始将寄存器的内容移到内存中。
In order to update a segment register, the corresponding segment descriptor must be modified in kernel memory and then reloaded into the segment register. 更新段寄存器时,与其相应的段描述符必须在核心内存中修改,然后重新载入段寄存器。
The CPU reads the data, shifts the bits in the register containing the data by the necessary amount of bit positions, and writes the data back to memory. CPU读取数据、移动包含数据的寄存器的位到必要的位置,然后将这些数据写回内存。
The most common analysis is data dependence analysis, which is to determine the instructions that use the variable ( register or memory location) modified by another instruction. 最通常的分析是数据依存性分析,它用来确定指令使用的变量(寄存器或内存位置)是否被另一条指令修改。
In this paper, based on the memory unit of the SIMD architecture, we propose a compilation scheme to exploit the partial reuse of the vector register data, and improve memory access efficiency in SIMD optimization. 因此,本文基于SIMD架构的访存特性,提出了一种向量寄存器部分重用的方法,以提高访存效率;优化体育教学方法,首先,须确立适度可行的教学目标;

Based on the jointed test action group ( JTAG) protocol, instructions and scan chain were introduced. With test access port ( TAP) module exchanging serial input with parallel output, register files and random access memory on chip were read or written in parallel. 在JTAG接口协议的基础上,增加指令和扫描链,同时通过测试访问端(TAP)控制把串行输入转换成并行输出,并行访问数字信号处理器的寄存器文件和片上存储器单元,实现嵌入式模拟器。
