通常来讲，CPU的结构可以大致分为运算逻辑部件、寄存器部件和控制部件等。

所谓运算逻辑部件，主要能够进行相关的逻辑运算，如：可以执行移位操作以及逻辑操作，除此之外还可以执行定点或浮点算术运算操作以及地址运算和转换等命令，是种多功能的运算单元。而寄存器部件则是用来暂存指令、数据和地址的。控制部件则是主要用来对指令进行分析并且能够发出相应的控制信号。

而计算机的内存又可以分为随机存取存储器（RAM）和只读储存器(ROM)。两者的区别在于，随机存取存储器能够与CPU直接的进行数据的交换，也可以将其称为主存。

Generally speaking, the structure of the CPU can be roughly divided into operation logic components, register components and control parts

And so on.

The so-called operational logic unit is mainly able to carry out related logical operations, such as: can perform shift operations and logical operations, in addition to can also perform fixed-point or floating point arithmetic operations and address operations and conversion commands, is a multi-functional operational unit. The register unit is used to temporarily store instructions, data and addresses. The control component is mainly used to analyze the instruction and can send out the corresponding control signal.

The computer's memory can be divided into random access memory (RAM) and read-only storage (ROM). The difference between the two is that the random access memory can exchange data directly with the CPU, and it can also be called main memory.
