目录号为 IC697CPX928 的 GE Fanuc 系列 90-70 模块是一个中央处理器 （CPU），主要用于执行下载到 CPU 内存的用户程序。该 CPU 模块是一个单插槽机箱，具有 80486DX4 微处理器，速度为 96 MHz，每个布尔函数执行时间为 0.4 μs。该模块配备了 6MB 电池备份 RAM 的板载内存和 256KB 非易失性用户闪存，其中还存储了 CPU 固件。

在结构上，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，由指令寄存器IR、指令译码器ID和操作控制器OC等组成。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，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OC，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：IC697CPX928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）。

存储单元：IC697CPX928包括CPU片内缓存和寄存器组，是CPU中暂时存放数据的地方，里面保存着等待处理的数据或已经处理过的数据。

此外，CPU模块还包含时钟和控制信号发生器。

The GE Fanuc Series 90-70 module with directory number IC697CPX928 is a central processing unit (CPU), mainly used to execute user programs downloaded to the CPU memory. The CPU module is a single-slot chassis with an 80486DX4 microprocessor with a speed of 96 MHz and each Boolean function execution time of 0.4 μs. The module is equipped with 6MB of on-board memory with battery backup RAM and 256KB of non-volatile user flash memory, where the CPU firmware is also stored.

In terms of structure, CPU modules can be logically divided into three main modules:

The control unit is the command and control center of the whole CPU, which is composed of instruction register IR, instruction decoder ID and operation controller OC. According to the user's pre-programmed program, it takes out each instruction from the memory in turn, determines what operation should be carried out through instruction decoding, and then sends a microoperation control signal to the corresponding component by operating the controller OC according to the determined timing.

Arithmetic unit: The IC697CPX928 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).

Storage unit: IC697CPX928 includes CPU on-chip cache and register group, which is the temporary storage of data in the CPU, storing the data waiting to be processed or the data that has been processed.

In addition, the CPU module contains a clock and a control signal generator.
