Introduction
Live electronic technology includes hardware (HW), the hardware plus software (HW + SW),[link widoczny dla zalogowanych], firmware (FW) 3 level comprises. This 3 levels can also be said that the application of modern electronic technology development stage 3. Since 1997, electronic technology has added a new level - System on Chip (SOC) levels. SOC-level technical concepts and the emergence of applied technology, marking the application of modern electronic technology into the SOC phase.
From each development stage, since the HW + SW stage, application of electronic technology to closely linked with the microcontroller. In the FW phase, the system as an important core technology firmware, microcontroller-based embedded technology Youyi, once again the application of modern electronic technology, one of the core technology and application technology for the SOC provides a firm foundation.
SOC for various applications of a new implementation technology. Implementation of this new technology to promote electronic systems industry in the past 3 years, tremendous changes have taken place for the application of information technology to provide a solid foundation, therefore, can be called the SOC revolution. At the same time, SOC single chip technology for a broader application area, the MCU application technology has revolutionized the change.
SOC Based on years of technology and technological development of microcontroller applications, the basic technical concept of the SOC and the relationship between the MCU and SOC technologies were discussed, that the SOC in the technical characteristics of MCU embedded applications.
One, SOC technology and application of concepts
So-called SOC technology, is a highly integrated, the firmware of the system integration technology. SOC technology design system using the core idea is to bring all of the application of electronic systems integrated in a single chip. SOC design in the use of technology applications, in addition to the external circuit that can not integrated or mechanical parts, all other systems all integrated circuits.
1. SOC system function integration is the core technology
Application of electronic systems in the traditional design, the need to function according to design requirements of the entire system of integrated modules that function according to design requirements to find the corresponding integrated circuit,[link widoczny dla zalogowanych], according to the design requirements of the technical indicators selected circuit design connection type and parameters. The results of this design is a feature-based integrated circuit device electronic system structure of distributed applications. The results can meet the design requirements of the design depends not only on the technical parameters of the circuit chip, and PCB layout with the entire system, the electromagnetic compatibility characteristics. Meanwhile,[link widoczny dla zalogowanych], digital technology systems have often involved in SCM should also have, therefore, must also consider the distributed system firmware characteristics of the circuit. Obviously, the realization of electronic systems, legacy applications, using the distribution function of integrated technology.
For the SOC, the application of electronic system design is based on functions and parameters to design the system, but is essentially different from traditional methods. SOC is not the function of the circuit-based distributed system integration technologies. But to features IP-based integrated technology system firmware and circuit. First, the function is no longer for the function of the realization of the integrated circuit, but the whole system firmware for the integrated circuit implementations, that is, the whole system using IP technology combined with the circuit. Second, the circuit design of the final results and characteristics of IP modules and firmware, whereas the block with the PCB circuit board manner and independent of the connection technology. Therefore, the results of the design features of EMC have been greatly improved. In other words, the design results are very close to the ideal design goals.
2. Firmware integration is based SOC design idea
Integrated design in the traditional distributed technology, the system's firmware properties are often difficult to achieve optimal, because the function used by the integrated technology is distributed. Under normal circumstances, functional integrated circuits used in order to meet face as much as possible, we must consider two design goals: a variety of applications to meet the requirements of the function of the control objectives; the other is to consider a larger range of applications to meet the functional and technical indicators. Therefore, the function IC (integrated circuit which is custom) must be I / O and control circuitry to attach a number to make the average user to get as much as possible the development of performance. However, the application of custom circuit design to achieve the best electronic system is not easy, especially with the firmware feature is a large dispersion.
For the SOC, the core technology from the SOC can be seen, the use of SOC technology applications for electronic system design and the basic design is to achieve system-wide firmware integration. Users only need to select and improve the various parts of the module and the embedded structure, we can achieve fully optimized firmware features without having to take the time to know the development of custom circuit technology. Firmware-based unexpected advantage is closer to the ideal system, the system can more easily meet the design requirements.
3. Embedded SOC system is the basic structure
In the use of SOC technology applications for electronic system design, you can very easily achieve the embedded structure. The realization of a variety of embedded structure is very simple, as long as the system need to select the appropriate kernel, and then asked to select the match according to the design of the IP module, you can complete the entire system hardware structure. Particular the use of intelligent integrated circuit technology, can more fully realize the whole system firmware features, make the system more close to the ideal design. Must be pointed out, SOC embedded structure of this application can greatly shorten the design cycle.
4.IP SOC design is based
Traditional applications is the electronic design engineers face a variety of customized integrated circuits, the use of SOC technology, electronic system design engineers are faced with a huge IP library, all the design work is based on the IP module. SOC technology enables applications for electronic system design engineers to become a device for the application of electronic design engineers. Thus, SOC is based on IP block-based design technology, IP is the basis for SOC applications.
5.SOC technology in the different stages
Application by SOC technology design phases of the electronic system shown in Figure 1. In the functional design stage, designers must fully consider the characteristics of the system's firmware and the firmware using a comprehensive functional design features. When the functional design is complete, you can enter the IP integrated stage. IP integrated phase of the mission using powerful IP library for system functionality I. P with the end of the first functional simulation to check whether the system design to achieve functional requirements. After the adoption of functional simulation is the circuit simulation, IP modules purpose is to check the circuit design functions can be achieved and meet the corresponding design specifications. The final phase of the design of manufacturing a good product and make the appropriate SOC testing in order to adjust the technical parameters to determine the application parameters.
II, SOC application of the concept
Modern science and technology is one important feature is the technical diversity, versatility and smart design of object-oriented. So-called technical diversity, is to realize an application with the electronic system can have many different designs to choose from; and different design means that you must use a different design and production technology. Variability of the so-called knowledge, is the application of modern electronic technology system, to achieve system goals and methods of the basic theory of the emergence of new knowledge as constantly changing. This change not only the application of electronic systems, technical indicators change, even change the overall structure of the system.
With modern applications of information and electronic technology continues to expand, more and more applications put forward special requirements. For example, the requirements of aerospace small, powerful systems, information applications and other proposed requirements of the individual are generally firmware technology could not do so. Especially in the civilian fields, personalized attention to the concept of product design to make use of electronic product updates extremely fast, and small quantities of many varieties are increasingly high requirements. This is the proposed low-volume products and the cost of integration and cost, product development cycle and cost and a series of problems.
SOC is a modern science and engineering to meet the requirements of the development of the modern generation application of electronic technology. Traditional idea that only large quantities of products have the possibility of integration, that has the price competitive advantage. Thus far, most small-volume products, especially the nature of the application of electronic systems are generally used HW, HW + SW or FW technology. But with the emergence of SOC,[link widoczny dla zalogowanych], develop and mature, this situation has occurred a great change. SOC is a modern electronic engineers design efficient and economic system, so that the traditional concept that the high-performance, high complexity, high cost of the embedded structure can be achieved through low-cost single chip.
1.SOC design concepts
SOC design concepts and traditional design concepts are completely different. In SOC design, the designer is no longer the face of the circuit chip; but rather to achieve the design features of the IP module library. Unnecessary in many of the module designer to search for the required circuit of the circuit chip,[link widoczny dla zalogowanych], just need to design features and firmware features, select the IP module. The integrated circuit design technologies and methods, the virtual elimination of information barriers device, because each application design is a dedicated integrated system, is a dedicated integrated circuits. In other words, SOC design concept is In a sense, that is, the user becomes integrated circuit manufacturer.
2. Efficient and convenient design tools
Since IP is the basis of SOC, therefore, must use the appropriate EDA software to complete design. If there is no convenient and efficient design tools, SOC design is just empty talk. In fact, the traditional application of electronic system design work on the EDA and other design software is no corresponding high demand, only required to provide appropriate facilities; and SOC design must be established based on the EDA. For example, the use of SOC technology design an intelligent temperature control system, because the entire system in a single chip, the user must be able to one of the CPU core, memory, A / D, analog amplifiers and other circuits for integrated simulation, it is clear, there must be EDA tools for an efficient and convenient to complete these tasks.
