英语翻译
A register is a storage location inside the processor.Registers in the control unit are used to keep track of the overall status of the program that is running.Control unit registers store information such as the current instruction,the location of the next instruction to be executed,and the operands of the instruction.In the ALU,registers store data items that are added,subtracted,multiplied,divided,and compared.Other registers store the results of arithmetic and logic operations.
An important factor that affects the speed and performance of a processor is the size of the registers.Technically,the term word size(word length) describes the size of an operated register,but it is also used more loosely to describe the size of the pathways to and from the processor.Currently,word size in general-purpose computer range is 16 bits to 64 bits.If the operand registers of a processor are 16bits wide,the processor is said to be a 16-bit processor.
Instruction codes
A digital computer is a general-purpose digital system; A general-purpose digital computer is capable of executing various micro-operations and,in addition,can be instructed as to what specific sequence of operations it must perform.The user of such a system can control the process by means of a program.That is,a set of instructions that specify the operations,operands and the sequence by which processing has to occur.The data processing task may be altered simply by specifying a new program with different instructions or specifying the same instructions with the different data.A computer instruction is a binary code that specifies a sequence of micro-operations for the computer.Instruction codes together with data are stored in memory.The control reads each instruction from memory and places it in a control register.The control then interprets the binary code of the instruction and processed to execute the instruction by issuing a sequence of control functions.Every general-purpose computer has its own unique instruction repertoire.The ability to store and execute instructions,the stored program concept,is the most important property of a general-purpose computer.

寄存器（register）是位于处理器中的存储部件.控制单元(control unit)的寄存器主要用来记录所有正在运行的程序状态.控制单元寄存器主要存储诸如现在运行的指令（instruction）,下一个即将运行指令的地址,指令运算对象（operand）等信息.在算术逻辑部件中,寄存器主要用来存储加减乘除和用来比较的数据项.其他的寄存器用来储存算术和逻辑运算的结果.
一个重要的影响运算器速度和性能的因素是运算器的大小.学术上用word size（字长）来形容操作数寄存器大小,也更宽泛的用来形容进出处理器的路径规模.现在,冬种用途的计算机中,字长的范围是从16位至64位.如果处理器的操作数寄存器是16位宽的,那么这个处理器就被称为16位处理器.
指令代码
数字式计算机是一种多用途的数字系统：一台多用途数字计算机可以
执行多种微操作,此外,还能够被指派完成必须完成的具有特殊顺序的指令.这个系统的使用者可以借助于一个程序来控制处理器.那个程序是一系列指明处理发生时的特定操作,运算对象和顺序的指令.
