With the rapid development of science and technology, information technology, electronic technology, automation technology and computer technology are increasingly integrated and become an important pillar technology in the field of science and technology in today's society. The R & D work in any field is closely related to these technologies, and their mutual intersection and penetration are becoming closer and closer.
As the frontier of information technology, it should include the following contents: microelectronics and Nano Electronics; RISC reduced instruction system and parallel computing technology; Multimedia and virtual reality technology; Software engineering, case software engineering development environment and object-oriented software technology developed according to people's general thinking method and cognitive process; Automatic control (in addition to the first and second generation control theories and systems, as well as the theories and systems of fuzzy control, artificial intelligence and neural network), and finally the science and technology related to modern communication... We briefly introduce microelectronics and Nano Electronics, electronic computer technology and modern communication.
Central processing unit (CPU) is another important aspect of integrated circuit technology. Its main function is to execute "instructions" for operation or data processing. The CPU of modern computers usually consists of hundreds of thousands to millions of transistors. In the 1970s, with the development of microelectronics technology, a complete CPU could be fabricated on a silicon chip the size of a fingernail. The most important measure of CPU performance is "speed", that is, how many instructions it can execute per second. In the early 1960s, the fastest CPU could execute 1 million instructions per second (often abbreviated as MIPs). In 1991, the speed of high-end microprocessors reached 50 million to 80 million times. At present, the reduced instruction system technology (i.e. reduction and reduction of complex instructions) and parallel operation technology (executing several instructions in parallel at the same time) that continue to improve the CPU speed are developing. In this field, Intel in Silicon Valley has always been in a leading position.
In addition, the combination of Optics and electronics has become optoelectronic technology, known as the tip of the tip, which has found a new way for the further development of microelectronic technology. Time magazine predicts that "the 21st century will become the optoelectronic era." It mainly owns laser technology, infrared technology, optical fiber communication technology, etc.
