　　CPU模块，全称中央处理器模块，是一种集成了CPU芯片和相关电路的组件，是计算机系统的核心部件。它的主要功能是执行各种指令和进行数据处理，通过时钟信号驱动，根据指令集和算法完成计算任务。

　　IC697CPM915 CPU模块从逻辑上可以划分成三个主要部分：

　　控制单元：这是整个CPU的指挥控制中心，IC697CPM915 负责协调整个电脑有序工作。它根据用户预先编好的程序，依次从存储器中取出各条指令，放在指令寄存器中，通过指令译码确定应该进行什么操作，然后通过操作控制器，按确定的时序，向相应的部件发出微操作控制信号。

　　运算单元：这是运算器的核心，可以执行算术运算(包括加减乘数等基本运算及其附加运算)和逻辑运算(包括移位、逻辑测试或两个值比较)。IC697CPM915 运算单元接受控制单元的命令而进行动作，即运算单元所进行的全部操作都是由控制单元发出的控制信号来指挥的。

　　存储单元：包括CPU片内缓存和寄存器组，是CPU中暂时存放数据的地方，里面保存着那些等待处理的数据或已经处理过的数据。IC697CPM915 CPU访问寄存器所用的时间要比访问内存的时间短，因此采用寄存器可以减少CPU访问内存的次数，从而提高CPU的工作速度。

　　CPU module, the full name of the central processor module, is a component that integrates the CPU chip and related circuits, and is the core component of the computer system. Its main function is to execute various instructions and data processing, driven by the clock signal, according to the instruction set and algorithm to complete the calculation task.

　　The IC697CPM915 CPU module can be logically divided into three main parts:

　　Control unit: This is the command and control center of the entire CPU, IC697CPM915 is responsible for coordinating the orderly work of the entire computer. According to the user's pre-programmed program, it takes out each instruction from the memory in turn, puts it in the instruction register, determines what operation should be carried out through the instruction decoding, and then sends a microoperation control signal to the corresponding component by operating the controller according to the determined timing.

　　Arithmetic unit: This is the core of the arithmetic unit and can perform arithmetic operations (including basic operations such as addition and subtraction multipliers and their additional operations) and logical operations (including shifts, logic tests, or comparisons between two values). IC697CPM915 operation unit accepts the command of the control unit and acts, that is, all the operations carried out by the operation unit are commanded by the control signal issued by the control unit.

　　Storage unit: including CPU on-chip cache and register group, is a temporary storage of data in the CPU, which stores the data waiting to be processed or has been processed. The IC697CPM915 CPU accesses registers in less time than it accesses memory, so using registers can reduce the number of times the CPU accesses memory, thereby improving the CPU's working speed.
