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.
Application
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.
FAQ about Embedded - DSP (Digital Signal Processors)
-
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 DSP in microcontrollers?
DSP (Digital Signal Processor) is a microprocessor specifically used to process digital signals. It is different from the traditional CPU (Central Processing Unit). DSP is mainly used in occasions that require a large number of floating-point operations, such as communications, audio processing, image processing and other fields.
The working principle of DSP is to convert the received analog signal into a digital signal, and then process and analyze these digital signals. DSP chip adopts Harvard structure, that is, the program and data are stored separately, and has a dedicated hardware multiplier, which can quickly implement various digital signal processing algorithms.

3. What is the difference between DSP and FPGA?
The main difference between DSP and FPGA lies in their design purpose, structure, programming method and applicable scenarios.
First of all, there are fundamental differences between DSP and FPGA in design purpose and structure. DSP (digital signal processor) is designed for digital signal processing, with a dedicated instruction set and hardware accelerator for efficient processing of digital signals. FPGA (field programmable gate array) is a programmable logic device that can be programmed according to user needs to realize various digital logic circuits. FPGA contains a large number of logic gates and triggers inside, usually using a lookup table structure, while DSP uses a Harvard structure, with separate data bus and address bus, allowing programs and data to be stored separately to increase processing speed.
In terms of programming methods, DSP is usually programmed through assembly or high-level languages (such as C/C++) and has a complete C language compiler. FPGA is designed through hardware description language, which has high flexibility but high programming complexity. DSPs are relatively easy to program because they are designed for specific types of computing tasks, while FPGAs offer greater flexibility but are more complex to program.
Finally, DSPs and FPGAs are suitable for different application scenarios. DSPs are suitable for tasks that require high-speed processing of large amounts of digital signals, such as communications, audio processing, image processing, and other fields. FPGAs are suitable for applications that require highly customized hardware acceleration, such as high-performance computing, complex signal processing, and more. The flexibility of FPGAs makes them more advantageous in projects that require frequent changes in functionality, while DSPs perform better in applications that require efficient processing of fixed algorithms.
