　　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，是计算机系统中的核心部件。它负责执行各种指令和进行数据处理，其工作原理是通过时钟信号驱动，根据指令集和算法完成计算任务。

　　IC697CPM914RR CPU模块从逻辑上可以划分成三个主要模块：

　　控制单元：是整个CPU的指挥控制中心，对协调整个电脑有序工作极为重要。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，然后向相应的部件发出微操作控制信号。

　　运算单元：IC697CPM914RR是运算器的核心，可以执行算术运算(包括加减乘除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)。

　　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，保存着等待处理的数据或已经处理过的数据。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. It is responsible for the execution of various instructions and data processing, its working principle is driven by clock signals, according to the instruction set and algorithm to complete the calculation task.

　　The IC697CPM914RR CPU module can be logically divided into three main modules:

　　The control unit is the command and control center of the entire CPU, which is extremely important 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 out the microoperation control signal to the corresponding component.

　　Arithmetic unit: IC697CPM914RR is the core of the arithmetic unit, which can perform arithmetic operations (including basic operations such as addition, subtraction, multiplication and division and their additional operations) and logical operations (including shifting, logic testing, or comparing two values).

　　Storage unit: including the CPU chip cache and register group, is a temporary storage of data in the CPU, saving the data waiting for processing or has been processed data. The time used by the CPU to access registers is shorter than the time used to access memory, so the use of registers can improve the CPU speed.
