빠른 부트 지원 홈게이트웨이 개발

Embedded Devices load PC-level operating system to support many functions. These operating systems has a demerit of long booting time instead of providing complex functions. These problems has been cognized importantly enough to affect on a sale of products, and many researches has been conducted to solve this problem. This paper explains about an applying of recent technologies to our custom home gateway device for reducing boot time. A new software was developed to analyze, based on this, we could know that boot loader and user space-initialzation take more boot time than linux kernel. Especially, user space-initialization should be optimized a lot for fast booting.
