From the world of radio in the world to a single chip
Modern computer technology, industrial revolution, the world economy from the
capital into the economy to knowledge economy. Field in the electronic world, from
the 20th century into the era of radio to computer technology in the 21st century as
the center of the intelligent modern era of electronic systems. The basic core of
modern electronic systems are embedded computer systems (referred to as embedded
systems), while the microcontroller is the most typical and most extensive and most
popular embedded systems.
First, radio has created generations of excellence in the world
Fifties and sixties in the 20th century, the most representative of the advanced
electronic technology is wireless technology, including radio broadcasting, radio,
wireless communications (telegraph), Amateur Radio, radio positioning, navigation
and other telemetry, remote control, remote technology. Early that these electronic
technology led many young people into the wonderful digital world, radio show was
a wonderful life, the prospects for science and technology. Electronics began to form
a new discipline. Radio electronics, wireless communications began e-world journey.
Radio technology not only as a representative of advanced science and
technology at that time, but also from popular to professional fields of science,
attracting the young people and enable them to find a lot of fun. Ore from the bedside
to the superheterodyne radio radio; report issued from the radio amateur radio
stations; from the telephone, electric bell to the radio control model. Became popular
youth radio technology, science and technology education is the most popular and
most extensive content. So far, many of the older generation of engineers, experts,
Professor of the year are radio enthusiasts. Fun radio technology, radio technology,
comprehensive training, from basic principles of electronics, electronic components
to the radio-based remote control, telemetry, remote electronic systems, has trained
several generations of technological excellence.
Second, from the popularity of the radio era to era of electronic technology
The early radio technology to promote the development of electronic technology,
most notably electronic vacuum tube technology to semiconductor electronic
technology. Semiconductor technology to realize the active device miniaturization
and low cost, so more popular with radio technology and innovation, and to greatly
broaden the number of non-radio-control areas.
The development of semiconductor technology lead to the production of
integrated circuit, forming the modern electronic technology leap from discrete
electronics into the era of era of integrated circuits. Electronic design engineers no
longer use the discrete electronic components designed circuit modules, and direct
selection of integrated circuit components constitute a single system. They freed the
