Size reduction of multi-purpose operating systems for application-specific

摘要

When employing a multi-purpose OS(Operating System) for an embedded system, its size reduction is one of inevitable problems This paper describes the size reduction of a multi-purpose OS for application-specific system by deleting the unused code of the OS for the application programs. We study two cases where unit of deletion is statement of program language, or procedure. We try how much size reduction can be performed by using an existing OS. The results show 10% ～30% of it is reduced under the condition where only the 'init' program is activated.
