DSP Digital Signal Processing (Digital Signal Processing) is a technology that uses computers or special processing equipment to digitize signals. It converts analog signals into digital signals, and uses efficient algorithms to sample, transform, filter, estimate, enhance, compress, identify and other operations, and finally gets a signal form that meets people's needs. Compared to general-purpose processors, DSPS typically have higher arithmetic throughput, lower latency, and more efficient memory management mechanisms, all of which are designed to meet the requirements of real-time signal processing.

DSP (Digital Signal Processing) technology is mainly reflected in the accurate processing of signals. It can efficiently perform complex operations such as signal analysis, noise suppression and feature extraction, and provide reliable data support for subsequent decision or control. In addition, DSP also has high-speed computing power and low power consumption characteristics, especially suitable for scenarios that require real-time processing of large amounts of data, such as audio processing, video codec, communication systems, image processing, control systems and robots, medical and bioinformatics and other fields.

• 1. What are the two types of DSP?

  DSP (digital signal processor) is mainly divided into two types: fixed-point DSP and floating-point DSP. The main difference between fixed-point DSP and floating-point DSP is that they process data in different ways and formats.
  Fixed-point DSP uses fixed-point number format for calculation. This format directly stores data and exponents in integer form in memory, eliminating multiplication and division operations in floating-point operations, thereby increasing the calculation speed. Fixed-point DSP chips are relatively low in price and power consumption, but the calculation accuracy is relatively low.
  Floating-point DSP uses floating-point format for calculations. This format can represent large or small numbers, with high calculation accuracy, and is suitable for occasions that require high-precision calculations. However, floating-point DSP chips are expensive and consume a lot of power.

• 2. What is built-in DSP?

  Built-in DSP is a technology that combines digital signal processing (DSP) functions with power amplifiers. It not only has the power amplification function of traditional amplifiers, but also accurately processes and adjusts audio signals through DSP chips to provide a higher quality music experience.
  The core advantage of built-in DSP lies in its powerful audio processing capabilities. Through DSP technology, audio signals can be optimized and managed to achieve active frequency division, delay processing, EQ debugging and other functions, thereby improving the performance of the audio system and making the sound clearer and more pleasant to listen to.In addition, DSP amplifiers also support parameter adjustment through computers, mobile phones and other devices, providing more flexible audio management solutions.

• 3. What are the three types of signal processors (DSP)?

  There are three main types of signal processors (DSP): enhanced DSP, VLIW structure, superscalar architecture, and SIMD structure hybrid structure.
  Enhanced DSP: This DSP has a highly optimized instruction set and structure that can quickly execute common signal processing algorithms. They are often used in applications that require high-speed signal processing.
  VLIW structure: DSP with VLIW (Very Long Instruction Word) structure can execute multiple instructions in one cycle, thereby increasing processing speed. This structure is suitable for applications that require high parallel processing capabilities.
  Superscalar architecture and SIMD structure hybrid structure: These structures combine the advantages of superscalar and SIMD (Single Instruction Multiple Data) technologies, can process multiple data in a single instruction cycle, and are suitable for application scenarios that require high-performance computing.
