三个部件组成，对协调整个电脑有序工作极为重要。指令寄存器:用以保存当前执行或即将执行的指令的一种寄存器。指令内包含有确定操作类型的操作码和指出操作数来源或去向的地址。指令长度随不同计算机而异，指令寄存器的长度也随之而异。计算机的所有操作都是通过分析存放在指令寄存器中的指令后再执行的。指令寄存器的输人端接收来自存储器的指令，指令寄存器的输出端分为两部分。操作码部分送到译码电路进行分析，指出本指令该执行何种类型的操作地址部分送到地址加法器生成有效地址后再送到存储器，作为取数或存数的地址。存储器可以指主存、高速缓存或寄存器栈等用来保存当前正在执行的一条指令。当执行一条指令时，先把它从内存取到数据寄存器(DR)中，然后再传送至IR。

指令划分为操作码和地址码字段，由二进制数字组成。为了执行任何给定的指令，必须对操作码进行测试，以便识别所要求的操作。指令译码器就是做这项工作的。指令寄存器中操作码字段的输出就是指令译码器的输入。操作码一经译码后，即可向操作控制器发出具体操作的特定信号。程序计数器:指明程序中下一次要执行的指令地址的一种计数器，又称指令计数器。它兼有指令地址寄存器和计数器的功能。当一条指令执行完毕的时候，程序计数器作为指令地址寄存器，其内容必须已经改变成下一条指令的地址，从而使程序得以持续运行。

The composition of three components is extremely important for coordinating the orderly operation of the entire computer. Instruction register: A register used to store instructions that are currently executing or about to be executed. The instruction contains an opcode that determines the type of operation and an address that indicates the source or destination of the operand. The length of instructions varies with different computers, and the length of instruction registers also varies accordingly. All computer operations are performed by analyzing instructions stored in instruction registers. The input end of the instruction register receives instructions from memory, and the output end of the instruction register is divided into two parts. The operation code part is sent to the decoding circuit for analysis, indicating what type of operation this instruction should perform. The address part is sent to the address adder to generate a valid address and then sent to the memory as the address for data retrieval or storage. Memory can refer to main memory, cache, or register stack used to store a currently executing instruction. When executing an instruction, it is first fetched from memory into the data register (DR) and then transferred to IR.

Instructions are divided into opcode and address code fields, consisting of binary digits. In order to execute any given instruction, the opcode must be tested to identify the required operation. The instruction decoder does this job. The output of the opcode field in the instruction register is the input of the instruction decoder. Once the operation code is decoded, specific signals for specific operations can be sent to the operation controller. Program counter: A counter that indicates the address of the next instruction to be executed in a program, also known as an instruction counter. It combines the functions of an instruction address register and a counter. When an instruction is completed, the program counter serves as the instruction address register, and its contents must have been changed to the address of the next instruction to enable the program to continue running.
