The DSP embedded structure is not the same as the DSP embedded system

The concept of embedded is inherently vague, and to understand these two words.

The difference depends on what the situation is.

The connection between embedded systems and DSPs: DSPs are a type of embedded systems.

Difference Between Embedded and DSP:

1. Manufacturer:

The manufacturers of DSP are mainly Agree, ADI, Motorola and TI; There are more than 100 embedded ** merchants, with a wide range of products.

2. Field: DSP mainly completes the function of high-speed data processing; At present, the application of DSP is more concentrated in the field of communication. Whereas, DSPs are the main choice for consumer electronics.

3. Supportiveness:

The trend of DSPs is higher computing speeds, with the advent of DSPs with 1GHz clocks, and increasing attention is paid to overall performance optimization; Embedded, on the other hand, is more application-specific and is supported by the industry's broader network of third-party DSP developers.

4. Maintenance and utilization:

Due to the requirements of the application, the embedded has relatively low power consumption, and the software of the DSP has stronger maintainability and reuse.

I think the DSP you mentioned here refers to Digital Signal Processor, which is a unique microprocessor, which is a device that processes a large amount of information with digital signals. It works by receiving an analog signal and converting it into a digital signal of 0 or 1. The digital signal is then modified, deleted, enhanced, and interpreted back to analog data or real-world format in other SoCs.

Not only is it programmable, but it also has a real-time running speed of tens of millions of complex instruction programs per second, far exceeding that of general-purpose microprocessors, and is an increasingly important computer chip in the digital electronics world. Its powerful data processing capabilities and high operating speed are the two most commendable features.

DSPs should be a part of embedded applications.

I don't know if it's right or not, I'm a newbie.

The embedded system is a combination of software and hardware, for example, the nios kernel in the FPGA is a SOPC embedded system, and for example, the Linux in RAM9 is also an embedded system, which has an operating system.

DSP is a door technology, that is, digital signal processing, of course, sometimes it also refers to a chip, such as a series, the embedded system you said and DSP are not necessarily related, hehe, but both are today's more popular technologies! I hope my answer is helpful to you!

In fact, DSP is also embedded, but job announcements tend to refer to ARM more.

DSP: Similar to MCU, but different, its computing speed is quite fast! It is mainly used for speed computing, compression, decoding, encoding, and other occasions for processing a large amount of data.

Features: Fast computing speed!

Embedded Systems: The scope of the description is even greater. In general, this is an embedded system, or a part of it.

Think about your computer's printer, some peripherals can be called embedded in the world. But now when it comes to embedded systems, it is generally associated with ARM chips. It's a 32-bit "microcontroller", I've always called him.

Hey! The kernel design is very classic, and now there are many people who use him to learn from him. **It is also slowly decreasing over time, and it is said that the lowest is now around $1.

DSP software engineer is a person who writes software for the existing DSP hardware system, and controls the DSP to achieve different functions through the software carried by different groups;

DSP hardware engineer is engaged in DSP hardware development, can be the production of DSP chips, can also be the DSP system board making personnel, generally speaking, DSP hardware engineers to design to specific hardware development, but also need to use a lot of CAD software to assist development, more difficult than software engineers.

To put it bluntly, a DSP software engineer is a person who uses a DSP, and a DSP hardware engineer is a person who does a DSP.

At present, the mainstream controller of China's electromechanical equipment is PLC, with the development of computer technology, embedded products in this field of rapid growth, and in some special applications to achieve a dominant position, the formation of a strong competitive pressure on small PLC, in some areas even appear to replace the PLC trend. For example, in the plastic machinery industry, special computers for plastic machinery based on embedded products have dominated the industry; In the elevator, the controller based on embedded products has occupied half of the country, and it occupies an absolute advantage in passenger elevators and high-speed elevators, and PLC only has a place in freight elevators and low-speed elevators; In high-end printing machinery, the printing machinery computer system based on embedded products is the most widely used control scheme.

Compared with small PLCs, embedded controllers have the advantages of strong computing and processing capabilities, convenient communication with PCs, low cost (compared with PLCs with the same performance indicators), optimized design for applications, and convenient user use.

Of course, there are also some problems with embedded controllers, the user's technical foundation is weak, not as common as PLC application development engineers, and the product needs to be developed by the application developer; Reliability is not as good as PLC; Products are not available everywhere like PLCs; The industry has strong characteristics and poor versatility.

Embedded controllers are usually provided by application developers, and some large device manufacturers develop their own embedded controllers. The cost of developing embedded special controller is higher, and the cycle is relatively long, so the current embedded controller is only used for large quantities, the use of relatively fixed control functions, and the overall cost and development cycle of the embedded controller are at a disadvantage relative to PLC for non-standard equipment with small batches.

The future of embedded controllers is bright for the following reasons:

2. The cost of the embedded controller system is advantageous;

4 major electromechanical equipment manufacturers have also begun to develop embedded controllers for their own devices;

5. The user base and technical base are gradually improved.
