学习嵌入式有前途吗?很多计算机行业的人都有这个问题。在日益信息化的社会，计算机和网络已***到我们日常生活的每一个角落。我们每个人，需要的已不再仅仅是放在桌上处理文档，进行工作管理和生产控制的计算机“机器”;各种各样的嵌入式系统在应用数量上已超过通用PC，任何一个人可能拥有嵌入式技术的各种电子产品，mp3、PDA、网络家电、智能家电、车载电子设备等等。而在工业领域中，使用嵌入式技术的数字机床，智能工具，工业机器人也在逐渐改变传统的工业方式。
学习嵌入式有前途吗?嵌入式系统技术已成为最热门的技术之一，但对于什么是嵌入式系统，什么样的技术又可称之为嵌入式技术，仍在讨论之中，我们可从广义上和狭义上讲：Broadly speaking, any special hardware and software systems with microprocessor can be called an embedded system. So, some people simply say: "Embedded system refers to the operating system and software integration features into computer hardware in the system." There is a view that embedded systems are "application-centric, computer technology, software and hardware can be cut to meet the specialized computer system "application system functionality, reliability, cost, size, power consumption strict requirements. From a functional point of view the latter application features better summed up the definition of embedded systems, embedded on the analysis of the fundamental concepts should be cut from the application.
In a narrow sense, that constitute a separate system using an embedded microprocessor (or more specifically refers to the 32-bit microprocessors), operating system independent and have certain features of the system may be referred to as embedded systems. In this definition, the typical embedded system using x86 small embedded computer motherboard, there are from Intel, Motorola and other small systems dedicated chips. We have now clearly see: embedded technology in the spring has come. No wonder one of the most popular embedded system technologies present.
And traditional computer and digital products than as a rookie after the PC era, the use of embedded technology development of products has its own characteristics:
1, since the use of a microprocessor embedded system, independent of the operating system, relative to a single function, so a large number of peripheral devices basically do not. Therefore, power consumption in volume and has its own advantages.
2, embedded system is a comprehensive technical disciplines will be computer technology, electronics and semiconductor technology and industry specific applications combining. Limited space and lack of embedded systems hardware and software resources must be efficiently designed for up to achieve higher performance in the same silicon area, so as to be more competitive on the choice of processor in specific applications force.
3, the height of the embedded system is a combination of software and hardware, in order to improve system reliability and speed of execution, software is generally cured in the memory chip or microprocessor itself. Implement system-on-chip technology, making products such as PDA has a more familiar user interface and mode of operation than traditional business affairs function better and more practical.
4, to adapt to distributed processing architecture and embedded Internet access demand, current systems generally require embedded with a plurality of standard network communication interface. External demand for networked, embedded devices must be equipped with communication interfaces, the corresponding need TCP / IP protocol support. Since the coordination needs of interrelated field apparatus and experimental appliances, embedded devices need to have IEEE1394, USB, CAN, Bluetooth communication interface, etc., but also need to provide appropriate communication network protocol and physical layer driver. In order to support specific programming models, such as the Web or wireless Web mode, the need to appropriate browser.
5, embedded system products have a longer life cycle, because of embedded systems in general and specific applications together, it is also upgrading and specific products simultaneously, so the embedded system products enter the market, generally have a relatively long The life cycle.
××× 90 years from the beginning of the last century, embedded technology in full swing, and communications products become the common development direction of consumer products, in the field of communications, radio and television collar and other widely used. Individual areas of embedded products are mainly personal business, as a personal mobile data processing and communications software gained popularity. Thus, the development of space technology is very vast number of embedded systems. Embedded systems are a hot research, prompted us to put into it. At the same time our research, we also found that as the study of microprocessor embedded systems research and hardware systems already quite a long time, so it is hardware or software, we are easy to get research information.
Through the above description, I believe you have a future embedded learn it, have a certain understanding. An embedded system is the Pillar of Atlas post-PC era technology, has reason to believe that the future of electronic technology is the world of embedded systems technology.
