摘　　要：系统调用是操作系统提供的一系列函数,它在嵌入式系统开发中起着重要的作用,驱动程序的设计和系统调用密切相关。因此,简单论述了嵌入式系统开发中驱动程序设计的重要性,说明了驱动程序的基本结构和实现原理。最后通过系统调用函数Write详述了系统调用函数实现的过程与机制,并总结了嵌入式Linux下系统调用的具体步骤。System-call is a series of functions of operating system, it is very important in development of embedded system, The design of driver program is in relation to system-call, The important of driver program design in development of embedded Linux system is de- scribed, and the basic structure and realization principium of driver program is described, finally process and mechanism of system-call function is expanded by example, the material steps of system-call in embedded Linux system are summarized.
