摘要
TI Davinci技术是一种先进的集成数字视频系统解决方案。首先介绍了Davinci技术芯片DM6446的硬件结构,然后介绍了基于这种结构的多种启动方式,并给出了一种能够多级启动的嵌入式MontaVista Linux系统内核剪裁方案,最后在DM6446开发板上运行嵌入式MontaVista Linux系统并查看了系统内核的内存使用情况。实验结果表明,文中的启动方案可以快速完成MontaVista Linux系统的启动,且内存占用较低。
TI Davinci technology is an advanced solution of integrated digital video system. The paperintroduces hardware architecture of Davinci technology chip DM6446 first, then analyses many bootmodes based on this architecture, and presents an embedded MontaVista Linux kernel cutting solutionwhich is capable of multistage boot, finally runs embedded MontaVista Linux system on DM6446development board and looking at the memory usage. The experimental results show that the solution canboot MontaVista Linux system rapidly and use few memory.
