PM511 ABB 处理器模块

描述

从功能上看，一般CPU的内部结构可分为：控制单元、逻辑运算单元、存储单元（包括内部总线和缓冲器）三大部分。其中控制单元完成数据处理整个过程中的调配工作，逻辑单元则完成各个指令以便得到程序最终想要的结果，存储单元就负责存储原始数据以及运算结果。浑然一体的配合使得CPU拥有了强大的功能，可以完成包括浮点、多媒体等指令在内的众多复杂运算，也为数字时代加入了更多的活力。

　　逻辑部件

　　英文Logic components；运算逻辑部件。可以执行定点或浮点算术运算操作、移位操作以及逻辑操作，也可执行地址运算和转换。

　　寄存器

　　寄存器部件，包括寄存器、专用寄存器和控制寄存器。 通用寄存器又可分定点数和浮点数两类，它们用来保存指令执行过程中临时存放的寄存器操作数和中间（或最终）的操作结果。 通用寄存器是中央处理器的重要部件之一。

From a functional perspective, the internal structure of a general CPU can be divided into three major parts: control unit, logical operation unit, and storage unit (including internal bus and buffer). The control unit completes the allocation work throughout the data processing process, the logic unit completes each instruction to obtain the final desired result of the program, and the storage unit is responsible for storing the original data and calculation results. The seamless integration enables the CPU to have powerful functions, capable of completing numerous complex operations including floating-point, multimedia, and other instructions, and also adds more vitality to the digital age.
Logic components
English Logic components; Operational logic components. It can perform fixed-point or floating-point arithmetic operations, shift operations, and logical operations, as well as address operations and conversions.
register
Register components, including registers, specialized registers, and control registers. General registers can be divided into two types: fixed point and floating-point, which are used to store temporary register operands and intermediate (or final) operation results during instruction execution. Universal registers are one of the important components of the central processing unit.
