What is DSP DSP (Digital Signal Processing) refers to the use of computers or special processing equipment to collect, transform, filter, estimate, enhance, compress, identify and other signals in digital form to obtain a signal form that meets people's needs (embedded microprocessor). Since the 1960s, with the rapid development of computer and information technology, DSP technology emerged and developed rapidly. In the past two decades, digital signal processing has been widely used in communication and other fields. Digital signal processing and analog signal processing are subfields of signal processing. The advantages of DSP technology: High accuracy High activity High reliability Time-division multiplexing The features of DSP technology: 1. Support for intensive multiplication operations 2. Memory structure 3. Zero overhead loops 4. Fixed-point computing 5. Special addressing mode 6. Prediction of execution time 7. Fixed-point DSP instruction set 8. Requirements for development tools Application: DSP is used primarily in areas of the audio signal, speech processing, RADAR, seismology, …
