翻译 在上世纪70年代初期，计算机仍然像怪物机器般隐藏在空调房和出现在由穿白大褂的技术人员手中。以前的一个大型计算机就想人民所知的那样由CPU，或中央处理单元组成。它好比一个钢柜满满的晶体管挤满了电路板。 翻译 计算机的必威体育精装版机器最近才从使用原始的聚集在一个封装晶体管集成电路到晶体管转换，这意味着CPU是一大堆设备。认为CPU可以减少到一个硅芯片只有指甲盖大小，是科幻小说里的东西。 How Does a CPU Work The component of the computer that fetches the instructions and data from the memory and carries out the instructions in the form of data manipulation and numerical calculations is called the CPU. It’s central because all the memory and the input/output devices must connect to the CPU, so it’s only natural to keep the cables short to put the CPU in the middle. It does all the instruction execution and number calculations so it’s called the Processing Unit 翻译 组件的计算机，取指令和数据从存储器进行数据处理和数值计算的形式被称为CPU。这是因为所有存储器和输入/输出设备必须连接到CPU，因此很自然的把电缆短把CPU中。它的所有指令执行和数据计算，所以它被称为处理单元 The CPU has a program counter that points to the next instruction to be executed. It goes through a cycle where it retrieves, from memory, the instructions in the program counter. It then retrieves the required data from memory, performs the calculation indicated by the instruction and stores the result. The program counter is incremented to point to the next instruction and the cycle starts all over. 翻译 该CPU具有程序计数器指向下一条要执行的指令。它通过一个循环中，从存储器中的指令，程序计数器。然后检索所需的数据从存储器，执行计算所表示的指令并存储结果。程序计数器是递增的点都在接下来的指令周期开始。 Microprocessor The microprocessor, or CPU, as some people call it, is the brains of our personal computer. 制作 介绍 Well, not everything about how they work, but enough to understand the importance of the latest features and what they do for you. It’s going to take more than one article to dig into the inner secrets of microprocessors. I hope it’s an interesting read for you and helps you recognize computer buzzwords when you’re making your next computer purchase. When the 1970s dawned, computers were still monster machines hidden in air-conditioned rooms and attended to by technicians in white lab coats. One component of a mainframe computer, as they were known, was the CPU, or Central Processing Unit.
