Xu Xiatian: From Radio to MP3 is not accidental - the electronics industry
" Semiconductor "This term has been and the" chatterbox ", Radio bundled together, a time when the semiconductor is synonymous with them. There is an interesting phenomenon: the founding of 60 years, our media player to the recorder then the radio evolution of MP3, it seems We only control the radio called "semiconductor." does not know the basis for the semiconductor industry as a whole, supporting every media player's history.
Nationwide "semiconductor" Misunderstanding "Semiconductor is the radio, this is misleading in understanding over the years, the radio only from Electronic Tube into a fresh example of the semiconductor, and is very widespread and popular, thus misleading many people. "China Semiconductor Industry Association, said of the teacher Xu Xiatian. I believe that many will come from that age old stunned, for several years, it is called is wrong.
Course, Xu also admitted that errors do widespread, almost a national misleading, because at that time and the environment that's been so understanding. Radio is only a small semiconductor development stage only, but at this stage in China for a long time.
Xu said, the semiconductor industry is the pillar industry of information technology, software, it is the pillar industry of information technology, hardware of all information. It includes data storage, information processing, intelligent operation and function of the expression and functional implementation. Battery, motor, rail, air and so are the final step in the realization of the power management by providing information, so information and power to achieve the entire automation hardware.
This leads to the semiconductor layer also means: We jump information from radio, which is entering an era of information industry. Hear the sound from your video now to see, to your life and now control every part of the electrical contact is a low-grade steel and semiconductors. Can be said that not only the radio, and now to MP3, are inseparable from the semiconductor. This end-product of evolution is accompanied by the development of semiconductor technology were completed.
From radio to MP3 is not accidental
Look at those old radios, some like a cupboard, and some kept a piece of cloth outside, and then look back to those expensive single card recorder and the music center. We looked down to see the hands of MP3, and conversion of this space-time gap is huge, then we have reason to believe that R & D personnel is certainly not thought about the people around them to convey Video Information tools into such and such appearance.
But all in Xu view, is not incidental. He said: "First, this change is inevitable. Secondly, back to the point of view or in front, thanks to the semiconductor on the contribution of information will be infinite. But based on our hard research and industrialization excellent conditions for the promotion of market-based industrial development. You can not just research, not industrial, but also in the application of the system and more with. R & D system, personnel training, technical conditions have to keep up with the industry. " Among the many things
development, the problem is solved step by step. Semiconductor industry has been resolved or are being resolved with all aspects of the problem. Xu has always insisted on?? On the information and make greater contributions to the semiconductor industry, born of the mission. In one radio has completed a very small primary products, I believe this information is far from something to be done.
The progress of semiconductor products to promote change in the whole terminal, we had the chance to think has become inevitable now. Because of these advanced features is now IC Higher level are integrated into a silicon chip, a feature originally a development to a number of functions can be integrated. From the large tube to a small integrated circuit, from the perspective of semiconductor development, MP3 radio into the present is indeed an inevitable trend.
From the radio to see the progress of mankind
