外文翻译--DSP产品的发展及应用.docVIP

外文原文 Development and application of DSP DSP concept first appeared in the last century 60s to 70s before they achieve some real-time processing by a computer and they were used for the high frontier. As DSP technology was closed to a large number of operations，and related to the completion of millions of instructions per second operation , it made it into a new unit on the MIPS (millions of instructions per second). 80s, some companies one after another designed for DSP processing technology processor, then became a high-performance DSP processor name. TI released in 1982, first DSP chip, called the TMS32010, this is a processing speed up to 5 MIPS processor. DSP development of the global market has bright prospects, DSP industry will become the most development potential in the 21st century a sunrise industry. ??? DSP digital signal processing technology can represent, but also can represent the digital signal processor, in fact, are inseparable, the former is the theory of technology, through the latter is the actual product. The combination of the real problems on the part of the solution and implementation of a program is called a digital signal processing solutions (DSPS). ?? ?DSPS is changing all aspects of our way of life, such as contact between people by phone turned personal communication. Human from the invention of the telephone number to 5 million phone users spent 70 years up to 5 million, and analog cellular phone users spent 14 years, while digital cellular phones (GSM is one of them) only took 5 years to achieve the same number of users .  Another example of our entertainment, VCD, DVD is replacing VHS recorders, digital TV started NTSC or PAL analog alternative system of TV. Mainly by the number of home theater A / V equipment composition, DSP not only give you surround sound, but also a variety of on-site for your virtual effects. ??? ?DSP increasingly comes into peoples lives, so the annual growth rate of DSP chips is more than 50% in rec
