摘　　要：随着嵌入式系统的综合化、智能化、复杂化发展,系统的数据代码量要求越来越大。基于PowerPC470处理器系统平台,针对系统内部资源不足的问题,分析了系统的u-boot启动流程,设计了一个二级启动的方法。该方法具有很强的通用性,同时适用于ARM和x86等架构的处理器系统,且集成度高、可扩展性强,可以满足嵌入式系统的实际应用需求。The quantity of data is increasing with the development of integration,intellectualization and complexity of embedded system.This paper analyzed the start-up process of the system,and designed a two-level start-up method to solve the problem of limited internal storage resources,which is based on PowerPC 470 processor platform.This method has the advantages of strong universality,high integration and scalability.It is also easily applied on ARM or x86 system.
