　　MVME2100 处理器模块的配置涉及多个方面，以下是一些主要的配置内容：

　　控制单元：MVME2100控制单元是整个CPU的指挥控制中心，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IR中，通过指令译码(分析)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：运算单元是运算器的核心，负责执行各种算术和逻辑运算。

　　存储单元：MVME2100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。它保存着那些等待处理的数据或已经处理过的数据。

　　在处理器模块的配置过程中，还需要考虑以下参数设置：

　　MVME2100 模块检测完成时间：用于设定“模块配置检测完成”信号的回答时间。当超过该时间未收到完成信号时，视为实际硬件配置与配置不符。该时间设定单位为100ms，默认设定为650。

　　参数传送到模块的时间：用于设定CPU中的参数传送到各模块的最大允许时间。时间设定单位为100ms，默认设定为100。对于有PROFIBUS-DP主站接口的CPU，可以通过本次参数来检测从站的启动情况。

　　The configuration of the MVME2100 processor module involves many aspects. The following are some main configuration contents:

　　Control unit: The MVME2100 control unit is the command and control center of the entire CPU, 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 IR, determines what operation should be carried out through instruction decoding (analysis), and then sends a microoperation control signal to the corresponding component by operating the controller OC, according to the determined timing.

　　Arithmetic unit: Arithmetic unit is the core of the arithmetic unit, responsible for performing various arithmetic and logic operations.

　　Storage unit: The MVME2100 storage unit consists of the on-chip cache and register group of the CPU, which is the place where data is temporarily stored in the CPU. It holds data that is waiting to be processed or has already been processed.

　　During the configuration of the processor module, the following parameter Settings need to be considered:

　　MVME2100 Module test completion time: used to set the answer time of the "Module configuration test completion" signal. If the completion signal is not received within the specified time, the actual hardware configuration is inconsistent with the configuration. The time setting unit is 100ms, and the default is 650.

　　Parameter transfer to module: Used to set the maximum allowed time for parameters in the CPU to be transferred to each module. The time setting unit is 100ms. The default value is 100. For a CPU with a PROFIBUS-DP master interface, you can use this parameter to check the startup status of the slave.
