For knowledge-intensive high-tech industries, the production process involves not only the processing of physical materials but also, and more importantly, the input, processing, and output of knowledge. Knowledge-based enterprises use specific knowledge resources acquired from external sources as raw materials, process them, transform them into knowledge products, and then output them to their users. The industry chain is divided along the lines of knowledge transfer. Figure 1 shows the knowledge-based industry chain of embedded software. Figure 1: Current Status of Upstream Development of the Embedded Software Knowledge Chain Structure From the 1970s, semiconductor process equipment and IC CAD equipment became an independent industry. By the 1980s, the production capacity of process equipment was quite strong, and the cost was also very high, thus separating it from the design stage and becoming two independent industries. In the 1990s, testing also became an independent industry. The most recent division of labor in the IC industry began in the late 1990s and is still ongoing: the division of system design and IP design within the IC design industry, forming the Chipless design approach. Its impact on the IC industry will be no less than the division between Fabless (chip design) and Foundry (chip manufacturing) in the 1980s. Figure 2. Scale and Growth of China's Embedded Software Industry from 2003 to 2006. An IP core (Intellectual Property Core) refers to a logic block or data block used in Application-Specific Integrated Circuits (ASICs) or Programmable Logic Devices (FPGAs). Designing commonly used but complex functional blocks in digital circuits, such as FIR filters, SDRAM controllers, and PCI interfaces, as modifiable modules allows other users to directly call these modules, greatly reducing the burden on engineers and avoiding repetitive work. As CPLDs/FPGAs become larger and more complex, the use of IP cores is a growing trend. Currently, major companies developing and operating IP cores include ARM, Amphion, DeSoc, MIPS Technologies, and Rambus. Taking ARM as an example, in 1985, ARM designed and developed its first RISC processor IP module with independent intellectual property rights, and in 1990, it transferred its IP patent rights to Apple for the first time. Currently, many companies worldwide, including IBM, TI, Philips, NEC, and Sony, use its IP cores to develop their own products. my country attaches great importance to the IP industry. In 2002, the "Integrated Circuit IP Core Standards Working Group (IPCG) of the Ministry of Information Industry" was established to formulate my country's IP core technology standards. Later, the "Software and Integrated Circuit Promotion Center (CSIP) of the Ministry of Information Industry" and the "Shanghai Silicon Intellectual Property Exchange Center (SSIPEX)" were established, laying the foundation for the application and promotion of IP standards. In August 2004, the National IP Core Library, established by CSIP, was completed and began to officially provide services to IC/SoC designers and manufacturers. In August 2005, the "China Silicon Intellectual Property Industry Alliance" (hereinafter referred to as the China IP Alliance) was officially established in Beijing. The alliance was initiated by CSIP, SMIC, Vimicro, Loongson Technology, Suzhou Guoxin, Datang Microelectronics, Zhixin Technology, Hisense, and many other organizations. The first batch of 51 enterprises and institutions to join the alliance included IC design companies, research institutions, domestic and foreign silicon intellectual property (IP core) providers, world-renowned EDA tool providers, and IC manufacturing companies. Downstream Development Status Embedded application systems have enormous development potential and market demand in China. The annual demand for information appliances is in the hundreds of millions, with each type of digital appliance having a market demand of tens of millions of units. Industrial control embedded systems have a demand of millions of units, and commercial embedded systems have a demand of several million units. Meanwhile, exports of embedded application products, especially communication equipment, are gradually increasing, securing a place in the global market. In 2006, China's embedded computer industry generated hundreds of billions of yuan in revenue, and both domestic and international markets provide a vast and promising space for China's embedded system industry. Embedded application systems have been widely applied in national defense, the national economy, and social life, penetrating various locations such as enterprises, the military, offices, laboratories, and individual homes. The main application areas in China's embedded system market are general-purpose home and enterprise applications, as well as applications closely related to people's lives such as property/security, telecommunications, commerce/finance, transportation, and media publishing. In addition, embedded applications are also gradually increasing in industrial, military, and medical fields. Current Status of the Embedded Software Industry Chain In 2006, the output value of China's embedded software industry reached 146.16 billion yuan, accounting for more than 20% of the entire software industry. However, due to the wide range of applications involved in embedded software and the different operating environments of various electronic devices, specialized design, development, and optimization are required for different electronic products. Therefore, conditions for industry monopoly are insufficient, and industry competition is highly fragmented. In the embedded software field, the main competitors exhibit a clear polarization. In platform software such as embedded operating systems, databases, and development tools, foreign brands hold an absolute advantage. Although there are a few domestic brands, they cannot compete with foreign brands in terms of application scale. On the application software side, domestic manufacturers have considerable companies occupying a dominant position in various sub-sectors. In general, the embedded system industry chain is not yet fully formed and is far from meeting the needs of various industries in China, such as transportation, communications, home appliances, industrial control, and military, for embedded system application products. It mainly relies on the self-sufficiency of embedded software products by terminal manufacturers. The domestic embedded software market is relatively underdeveloped, lacking specialization and social integration. The embedded software industry cluster in the Chinese market has not yet fully developed, with gaps in the industry chain and insufficient collaboration. However, as industry application cycles shorten, the self-sufficient development model is increasingly unable to adapt to fierce market competition due to the high and long-term investments in technology development, verification, and optimization. Independent embedded software providers, especially embedded operating system, embedded database, and embedded middleware vendors, will play an increasingly important role, and the entire embedded software industry chain will gradually move towards a stage of collaborative development.
