what is embedded system?

Embedded systems are user-oriented, product-oriented, application-oriented, it must be combined with the specific application will have vitality, it has more advantages. It can be understood the meaning of these three dimensions, namely, the embedded system is closely integrated with the application, it has a strong specialization, combined with the actual system needs to be a reasonable reduction of use.

Embedded system is the advanced computer technology, semiconductor technology and electronic technology and specific applications in various industries, after the combination of the product, which is decided that it must be a technology-intensive, capital-intensive, highly decentralized and innovative knowledge integration system. Therefore, the involvement of embedded systems industry, there must be a correct position, such as lcd module, or lcm. For example, Palm PDA reason why the field of more than 70% market share, because its based on the personal consumer electronics, focusing on the development of graphical user interface and multi-task management; and Wind River's Vxworks reason why the car was applied on Mars, it is because of its high real-time and high reliability.

Embedded system application requirements must be cut on the hardware and software to meet the application functionality, reliability, cost, size and other requirements. So, if we can establish a relatively common hardware and software base, and to adapt their needs to develop a system, is a good development model. The current core of embedded systems is often a few tens of K to K micro-kernel, according to the actual function of the use of extension or reduction, but due to the presence of micro-kernel, so this expansion can be carried out very smoothly.
