描述

中央处理器

CPU 948 R，替代 6ES5948-3UR21 和 6ES5948-3UR22 - 宽幅型

以下版本的 CPU948-3UR23 可用作兼容的冗余对：

3、4 和 5，带有新版本 6 的 CPU

较旧的 CPU 版本 1 和 2 与新版本不兼容。这些版本只能离线更新

如果版本 <= 5，则更新过程

更换第一个 CPU 948：

冗余模块必须按如下方式更换：

将备用CPU 948R切换为停止。

关闭电源（电源关闭）。

拔下 CPU 模块（注意 EGB 说明）

安装第一个 CPU 948：

已将更新的CPU 948模块插入已关闭的机架部分。

将操作模式开关设置为位置 STOP。

打开电源模块。

重置 CPU 948 （“urlöschen”;在将开关位置保持为“Urlöschen”的同时，将

操作模式从 STOP 切换到 RUN）。

启动 CPU 948（同时保持开关位置为“复位”），切换操作模式开关

从 RUN 到 STOP，再从 RUN 到 RUN）。

正在更新新的 CPU。

启动后，CPU 处于待机模式。

安装第二个 CPU 948

3 分钟后，主 CPU 可以关闭

如上所述的第一个 CPU 的进一步步骤

CPU，AP 再次以冗余模式运行。

中央处理器（英文名：Central Processing Unit，简称CPU）是一块超大规模的集成电路，是计算机的运算和控制核心，其作用类似于人脑，负责对数据的加工处理和各种控制信号的发送。主要功能是解释执行计算机指令来完成计算，基本功能是指令顺序控制、操作控制、时间控制和数据加工。中央处理器与内部存储器和输入/输出设备合称为电子计算机三大核心部件。

6ES5948-3UR23中央处理器主要包括运算器、控制器、高速缓冲存储器，以及实现它们之间联系的数据、控制其状态的总线。其中，运算器用于完成算术运算、逻辑运算和数据传送等数据加工处理任务；控制器根据存放在存储器中的指令序列（程序）进行工作，并由一个程序计数器控制指令的执行。

6ES5948-3UR23中央处理器的运作原理可以分为四个阶段：提取、解码、执行和写回。中央处理器从存储器或高速缓冲存储器中取出指令、放入指令寄存器，并对指令译码、执行指令。6ES5948-3UR23中央处理器的发展经历了真空管、晶体管、集成电路和大规模集成电路、超大规模集成电路几个时代。概括起来，中央处理器架构主要有4种：ARM、x86、MIPS、Power。目前，在移动芯片领域，ARM架构的芯片占据了90%以上的市场份额，在个人计算机和服务器市场上，英特尔x86处理器占据超过90%的市场份额。

Description

Central processing unit

CPU 948 R, replacement 6ES5948-3UR21 and 6ES5948-3UR22 - wide format

The following versions of CPU948-3UR23 are available as compatible redundant pairs:

3, 4, and 5, with new version 6 cpus

Older CPU versions 1 and 2 are not compatible with newer versions. These versions can only be updated offline

If version <= 5, update process

Replace the first CPU 948:

Redundant modules must be replaced as follows:

Switch the standby CPU 948R to stop.

Power off (power off).

Remove the CPU module (note the EGB instructions)

Install the first CPU 948:

The updated CPU 948 module has been plugged into the closed section of the rack.

Set the operation mode switch to position STOP.

Turn on the power module.

Reset the CPU 948 (" urloschen "; While holding the switch position as "Urloschen", the

The operation mode is changed from STOP to RUN.

Start CPU 948 (while holding the switch position to Reset) and switch the operating mode

RUN to STOP, RUN to RUN).

A new CPU is being updated.

After startup, the CPU is in standby mode.

Install the second CPU 948

After 3 minutes, the main CPU can be shut down

Further steps for the first CPU as described above

CPU, the AP again runs in redundant mode.

Central processor (English name: Central Processing Unit, referred to as CPU) is a large scale integrated circuit, is the computing and control core of the computer, its role is similar to the human brain, responsible for data processing and various control signals sent. The main function is to interpret and execute computer instructions to complete the calculation, and the basic function is instruction sequence control, operation control, time control and data processing. The central processing unit, together with internal memory and input/output devices, is called the three core components of the electronic computer.

The 6ES5948-3UR23 central processing unit mainly includes an arithmetic unit, a controller, a cache memory, and the data to realize the connection between them and the bus to control its state. Among them, the arithmetic device is used to complete the data processing tasks such as arithmetic operation, logic operation and data transmission. The controller works according to a sequence of instructions (programs) stored in memory, and a program counter controls the execution of the instructions.

The operation principle of the 6ES5948-3UR23 CPU can be divided into four stages: extraction, decoding, execution and write back. The central processor takes out the instructions from the memory or cache, puts them into the instruction register, interprets and executes the instructions. The development of 6ES5948-3UR23 central processing unit has experienced several eras of vacuum tubes, transistors, integrated circuits, large-scale integrated circuits, and very large scale integrated circuits. In summary, there are four main CPU architectures: ARM, x86, MIPS, and Power. Currently, in the field of mobile chips, ARM-based chips account for more than 90% of the market share, and in the personal computer and server markets, Intel x86 processors account for more than 90% of the market share.
