System features of embedded computers

1. Embedded systems are typically application-specific. The biggest difference between embedded CPU and general-purpose is that embedded CPU mostly works in a system designed for specific user groups, it usually has the characteristics of low power consumption, small size, high integration, etc., and can integrate many tasks completed by the board in the general-purpose CPU in the chip, which is conducive to the design of embedded systems tends to be miniaturized, the mobility ability is greatly enhanced, and the coupling with the network is becoming more and more close.
2. Embedded system is a comprehensive technical discipline that combines computer technology, semiconductor technology and electronic technology with specific applications in various industries. Due to the relative shortage of space and resources, the hardware and software of embedded systems must be designed efficiently, tailored, eliminate redundancy, and strive to achieve higher performance on the same silicon area, so that the choice of processor can be more competitive in specific applications.
3. Embedded systems and specific applications are organically combined, and its upgrading is also synchronized with specific products, so once embedded system products enter the market, they have a long life cycle.
4. In order to improve the execution speed and system reliability, the software in the embedded system is generally solidified in the memory chip or single-chip microcomputer itself, rather than stored in a carrier such as a disk.
5. The embedded system itself does not have the ability to bootstrap development, even after the design is completed, the user usually cannot modify the program function in it, and must have a set of development tools and environment to develop.
