Embedded systems are products of combining advanced computer technology, semiconductor technology, and electronic technology with specific applications in various industries. This inherent characteristic determines that they are inevitably technology-intensive, capital-intensive, highly decentralized, and constantly innovating knowledge integration systems. In today's increasingly information-driven society, computer and network applications have permeated every aspect of daily life. Various electronic products using embedded systems are ubiquitous, such as everyday mobile phones, cameras, medical instruments, automobiles, and even equipment in industrial control, aerospace, and aviation. In economically developed countries, the average household owns 255 embedded systems, and the average car has 35. The application of embedded systems is expanding widely into numerous fields such as industry, military, communications, transportation, finance, healthcare, meteorology, and agriculture. As one of the two major categories of computer systems, dedicated computer systems, namely embedded systems, have far surpassed traditional general-purpose computer systems in terms of application numbers. 95% of the world's microprocessor production is used in embedded systems, nearly 10 times that used in general-purpose computer systems. Moreover, every $10 billion spent on microprocessor chips generates $200 billion in embedded system output, bringing $1 trillion in benefits from embedded system application products. Embedded systems are primarily used in equipment and products requiring digitalization, intelligence, and networking. Their application not only improves people's lives but also transforms traditional industrial production, operation, and service methods, promoting the integration of informatization and industrialization in related enterprises, and generating substantial social and economic benefits. Currently, there are no specific statistics on the output value of embedded systems applications in my country. However, existing software output statistics show that in 2007, my country's software industry achieved revenue of 583.43 billion yuan, of which: software technology service revenue was 137.38 billion yuan, accounting for 23% of the total software industry revenue, 6.7 times that of five years prior; embedded software revenue was 141.62 billion yuan, accounting for 24.3%, 4.3 times that of five years prior; software product revenue was 178.28 billion yuan, accounting for 30.5%, roughly the same as five years prior; and system integration revenue was 106.77 billion yuan, accounting for 18.3%, a decrease of 2.9 percentage points compared to five years prior. Among the top 100 software companies announced by the state each year, most of the top 10 are embedded system application companies. Embedded systems are dedicated computer systems. Regardless of their application, embedded systems share the same basic function: achieving different application objectives by running different embedded software. Although embedded systems differ significantly from general-purpose computer systems in external shape, application targets, and operating environments, their basic components and operating methods are identical. Just as general-purpose computer systems consist of hardware and software, embedded systems also consist of hardware and software. The hardware of a general-purpose computer system comprises an arithmetic logic unit (ALU), control unit, memory, interfaces, buses, and power supply; the hardware of an embedded system consists of components with similar functions. General-purpose computer systems have external devices such as keyboards, monitors, mice, external storage devices, printers, and scanners. Embedded systems, in addition to being able to connect to almost all external devices required by general-purpose computer systems, also have commonly used external devices for data positioning, acquisition, conversion, transmission, and driving functions, such as sensors, relays, reed switches, phototubes, limit switches, and motors. From a software classification perspective: the software of a general-purpose computer system consists of system software, support software, and application software; the software of an embedded system also consists of these three parts. From an operational perspective: general-purpose computer systems can operate independently or via networking in a centralized or distributed manner. Embedded systems can also operate independently or via networking in a centralized or distributed manner. Therefore, both embedded systems and general-purpose computer systems are computer systems. However, embedded systems and general-purpose computer systems differ in many aspects, including external shape, application targets, working environment, and technical specifications. Embedded systems have three main characteristics: first, they are ubiquitous; second, they combine hardware and software, integrating them to meet application and design needs; and third, they are tailored to specific applications, requiring minimal redundancy in both software and hardware. Currently, embedded systems and general-purpose computer systems are developing in two incompatible technological directions. The development direction of general-purpose computer systems is to continuously improve speed and storage capacity, while the development direction of embedded systems is towards ultra-small size, ultra-low cost, high reliability, and easy coupling. When a general-purpose computer system is specifically designed to serve a particular task, it can also be called a dedicated computer system; for example, a financial management computer system or a human resources management computer system. These general-purpose computer systems, after removing specialized service tasks, can serve other tasks either exclusively or simultaneously after software replacement, or even without software replacement. Embedded systems, however, are different. Their hardware and software are "tailor-made" for specific applications, working only for those customized applications; they are truly dedicated computer systems. Embedded systems are dedicated computer systems that move off the desktop and out of the computer room, running embedded in application devices. Therefore, they are not called dedicated computer systems to distinguish them from certain dedicated systems within general-purpose computer systems. Developing Embedded Systems with a Liberated Mindset General-purpose computer systems, through software design including computer-aided design, computer-aided manufacturing, scientific computing, and engineering design, have realized an intellectual platform substitution. The intellectual platform model of general-purpose computer systems has driven the intellectual embedding of embedded systems, resulting in two domains in modern computing: the domain of general-purpose computer systems and the domain of embedded systems. In the embedded systems domain, intellectual embedding involves embedding the embedded system into an object system, providing an intellectual embedding model. The intellectual platform model of general-purpose computer systems and the intellectual embedding model of embedded systems represent two models of the computer industry revolution. General-purpose computer systems help humanity understand the world; embedded systems help humanity transform the world. Embedded systems are a recently emerging and popular field in the computer industry revolution. Embedded systems are the product of combining advanced computer technology, semiconductor technology, and electronic technology with specific applications in various industries. This inherently determines that it is a technology-intensive, capital-intensive, highly decentralized, and constantly innovating knowledge integration system. With the advent of the post-PC era, the application of embedded systems exhibits characteristics such as increased system complexity, diversified applications, hardware intensification, and software platformization. The rapid development and widespread application of embedded systems are continuing to deepen the computer industry revolution. my country's software and integrated circuit industries have received nearly 10 years of support from State Council Document No. 18 and related preferential policies, achieving significant development. However, there have been few breakthroughs in key technologies and processes, a lack of independent intellectual property rights, and the gap with advanced countries' industries has not yet significantly narrowed. These problems are related to the rapid development of the software and integrated circuit industries, the difficulty of catching up, the high technical difficulty of high-end technologies, and the industrial development environment and national support policies. It is necessary to liberate thinking and conduct an objective and effective analysis of the relevant national preferential policies that have been supporting the industry in the past. The analysis focuses on: whether to continue using tax rebates or tax the service industry; whether to continue supporting the development of the entire industry or focus on supporting key technologies and processes; whether to encourage fierce competition among enterprises to strive for size or guide resource integration and complementary advantages among enterprises, allowing a few to grow larger through mergers or franchising; and whether to continue fully supporting the development of the software and integrated circuit industries or to consider the construction and development of the upstream and downstream industrial chains of these two industries. Embedded systems are fundamental to the development of embedded software and integrated circuits. Today, in the modern computer industry revolution, the software and hardware technologies of general-purpose computer systems have entered a monopoly stage. PCs account for 90% of general-purpose computer systems, and 80% of PCs use Intel's 8x86 architecture. The chips used are basically from a few integrated circuit companies such as Intel, AMD, and Cyrix. Regarding the essential operating systems and word processors for PCs, Microsoft's Windows and Word systems account for 80%-90%. Furthermore, other applications can be used in conjunction with the operating system. Embedded systems, however, are a decentralized application industry, brimming with competition, opportunities, and innovation. No single series of processors, operating systems, or a few companies and products can monopolize the entire embedded systems market. Therefore, products and technologies in the embedded systems field are inevitably highly fragmented, leaving ample room for innovation for small and medium-sized high-tech companies across various industries and creating numerous opportunities to acquire independent intellectual property rights. Furthermore, various application fields in society are constantly evolving, and user needs are becoming increasingly refined. Embedded systems must also develop in tandem, which constitutes a powerful driving force for their development. In embedded systems, hardware is the support, and software is the soul. Every embedded system requires embedded software to provide flexible and diverse specialized functions to meet application requirements. The wide range of applications in embedded systems determines the crucial role of embedded software, making it a fundamental component of the embedded systems industry. In addition, application-specific integrated circuits (ASICs) are another important foundation of the embedded systems industry. The foundation of the embedded systems industry lies in application-centric integrated circuit design technology and application-oriented software product development technology. The rapid development of embedded systems today primarily relies on technological advancements in the software and integrated circuit industries; simultaneously, the development of embedded systems has become a major market for both the software and integrated circuit industries. Embedded software can only be integrated into digital, intelligent, and networked service products across various industries through embedded system hardware; enterprises can only proceed with integrated circuit design after mass-producing and stabilizing products with embedded systems. Without the development of embedded systems, embedded software will be like a tree without roots, and the integrated circuit industry will be like cooking without ingredients. Without the development of embedded systems, there will be a disconnect between embedded software and the integrated circuit industry, and the integrated circuit design and manufacturing equipment imported at great expense will be idle or underutilized.
