Digital signal processor (DSP) is a processor composed of large-scale or very large-scale integrated circuit chips to complete the task of digital signal processing.
Digital signal processor (DSP) is the theory and technology of digital signal representation and processing. Digital signal processing and analog signal processing are subsets of signal processing. The purpose of digital signal processing is to measure or filter continuous analog signals in the real world.
Therefore, before digital signal processing, the signal needs to be converted from analog domain to digital domain, which is usually realized by analog-to-digital converter. The output of digital signal processing is often converted to the analog domain, which is realized by Digital Analog Converter to analog converter.
Digital signal processor DSP is a processor composed of large-scale or very large-scale integrated circuit chips, which is used to complete a certain signal processing task. It is gradually developed to meet the needs of high-speed real-time signal processing tasks. With the development of integrated circuit technology and digital signal processing algorithm, the implementation method of digital signal processor is also changing, and the processing function is constantly improved and expanded.
Digital signal processor is not only limited to the audio and video level, it is widely used in communication and information systems, signal and information processing, automatic control, radar, military, aerospace, medical, household appliances and many other fields.
In the past, general microprocessors were used to complete a large number of digital signal processing operations, which was slow and difficult to meet the actual needs; Using bit chip microprocessors and fast parallel multipliers at the same time was once an effective way to realize digital signal processing, but this method has many devices, complex logic design and program design, large power consumption and high price.
The emergence of digital signal processor DSP solves the above problems well. DSP can quickly realize the signal acquisition, transformation, filtering, estimation, enhancement, compression, recognition and other processing, in order to get the signal form that meets people's needs.
