摘要
在国产化过程中,PowerPC芯片与天脉环境下的开发日益趋多,其中必须进行全地址空间配置。以上述环境为平台,阐述了从NAND Flash与Nor Flash上电到代码运行的原理与异同;结合应用,着重分析了上电引导过程中的地址空间配置并深入讨论了MMU及Cache的特性;研究了MSL与OS下地址空间间的联系与配置过程,为实际开发提供了帮助。
During the process of percentage of home-made parts,the development based on Power PCand Acore OS be common,the configration of address space is essential. Under the environment,First expounding the course and different of code if electrified under the NAND Flash or Nor Flash; combine the application,then analyse the distributing address space of BOOT,canvass the characteristic of MMU and Cache; last introduce the address space of MSL and OS,the article will provide guides for development.
