请大家帮我概括一下这段英文的主要内容,急
The first CPUs were from relay constructed as in the case of the Zuse Z3 ,followed by electron tubes like the Eniac .In the 1950s,the unreliable electronic tubes were replaced by transistors,which also reduces power consumption of the computer.With the availability of integrated circuits could be further reduced,the main processors,the CPU could soon be a single cabinet housed in what the term mainframe so "main frame",or "main cabinet" led.The next step CPU fit on a single circuit board in such a cabinet,there was first computer with multiple CPUs (multiprocessor) for higher computing power.At the same time was the class of mini-computers that are no longer needed its own air-conditioned room for the operation and its performance was sufficient for the supply of working groups.
The continuing increase in integration density led to the early 1970's first major processors have been built,the place had on a single chip,the microprocessor .Initially ridiculed because of their relatively low efficiency (it is claimed that an IBM engineer to the first microprocessor to have said:"Nice,but what's the point),have microprocessors now replaced all previous techniques for the construction of a main processor.
First mention of the term CPU go back to the beginning of the 1950s.For example,in a brochure from IBM (705 EPDM) of 1955,the term "Central Processing Unit" first announced,later supplemented by the abbreviation in parentheses CPU and then only used in its short form.Older IBM brochures use the term not,for example,the booklet "Magnetic Cores for Memory in Micro Seconds in a Great New IBM Electronic Data Processing Machine for Business" of 1954,the IBM 705 is also shown although,at the appropriate places,but only to "data processing" is mentioned.
主要是将cpu历史的,

第一个cpu都来自继电器误解为在这个例子中Zuse Z3,其次是电子管像Eniac.在20世纪50年代,不可靠的电子管代替晶体管,这也降低功耗的计算机.与有效性的集成电路能进一步降低,主要的处理器,CPU不久将坐落在一个单一的内阁”这一主机这么“主框架”,或者“主要内阁”的主导.下一步CPU装在一个单一的电路板在这样一个小巧的第一台电脑,有非常多,艺术设计多处理器)与多个CPU(更高的计算能力的云.在同一时间,是班上的微型电脑,不再需要它自己的空调的房间里操作及性能已足够的供应工作小组.
在集成密度的不断增加导致了早1970年的第一次大规模处理器已经建成,这个地方在一个芯片上,微处理器.最初的嘲笑,因为他们的相对效率较低(据宣称IBM的工程师到第一个微处理器曾经这样说:“很好,但你指的是什么),有微处理器现在取代以前的一切技术兴建的主处理器.
这个词是最先提到的CPU回到开始的20世纪50年代.例如,在一份小册子从IBM(三元乙丙橡胶)的卫生署1955年,术语“中央处理器”首次公布了,后来又相辅相成,简称CPU,然后在括号内只用于其缩写形式.年长的IBM小册子使用术语,例如,这本小册子“磁芯在微秒的记忆,一个伟大的新IBM的电子数据处理机器为商业”的1954年,IBM 705号同样显示虽然,在适当的地方,却只提到"数据处理”.

最早是继电器式，如Zuse Z3
后来是电子管式，如ENIAC（这个学过计算机的都知道吧）
1950年代起，晶体管替代电子管
再后来，大规模及超大规模集成电路
下一步是处理器的分化：更强劲的多核处理器以及更小巧节能的微型处理器（嵌入式处理器）。我是要的英文概括，能重新写下吗？谢谢你！！...
