IHS released a white paper on the automotive chip shortage, “Managing the 2021 automotive chip famine”, without taking into account the Texas power outage and the Japanese earthquake, it is believed that the chip shortage will lead to a global production cut of 1 million cars in Q1 2021, and the shortage will continue until Q3.
What is the role of the chip in the automotive system?
With the progress of information technology, automotive SoC system has become a must for many cars, and automotive SoC is the high-end application of embedded technology in automotive electronics, for the realization of the control, computing, and communication functions of the car, but also the key to the development of smart cars.
Currently on the market SoC performance indicators embedded systems are an important part of the field of pan-computing, is a dedicated computer system to complete a specific function in the embedded object host system. Embedded systems have the advantages of small size, low power consumption, high integration, and the ability to communicate and integrate between subsystems. With the development of automotive technology and the continuous progress of microprocessor technology, it has been widely used in automotive electronics. At present, from body control, chassis control, engine management, active and passive safety systems to in-vehicle entertainment and information systems are inseparable from the support of embedded technology.
The role of automotive embedded SoC system
Automotive embedded SoC system is the product of the transition of embedded system to the high-end application of real-time multi-task management, network coupling and communication, which greatly improves the real-time, reliability and intelligence of automotive electronic system. In addition to the common characteristics of ordinary embedded systems, it also has many advantages, such as strong support for real-time multitasking management, interrupt response time of 1~2μs; strong storage area protection function; reasonable task scheduling with the support of embedded real-time operating system, making full use of system resources; hardware structure and software functions have strong scalability, system integration.
The system hardware has enhanced anti-interference capability, and can adapt to various working environments such as high temperature, humidity, vibration, and electromagnetic radiation; the real-time operating system supports software multi-threaded structure, which enhances the software anti-interference of the system; it provides powerful network communication functions, supports corresponding communication networking protocol software and physical layer driver software, provides fault-tolerant data transmission capability and larger communication bandwidth, etc.
The development of the automotive SoC system is also inseparable from the support of software because the software makes hardware more practical, and only the system that more users like is the best system.
