MCU技术、FPGA技术和DSP技术，是目前数字电路系统设计领域公认的三大基础性技术，以这三类技术形成的应用系统也是目前嵌入式系统的主要表现形式。
　　　　其中MCU技术最为经典、应用成熟、受众面广。近年来，MCU技术发展迅速，已从传统设计技术走向现代设计技术，其功能、速度、资源正在不断加强，更加易于解决电子系统的嵌入性、微型化、低功耗、高可靠性和低价格等问题。(MCU technology, FPGA technology and DSP technology are the three basic technologies recognized in the field of digital circuit system design, and the application system formed by these three technologies is also the main form of embedded system.
The MCU technology is the most classical and mature application, wide audience. In recent years, the rapid development of MCU technology, from the traditional design technology to the modern design technology, its function, speed, resources are constantly strengthened, more easy to solve the electronic system embedded, miniaturization, low power consumption, high reliability and low price etc..)
