• Computer software consists from two types of program. One is kernel program running with kernel mode, the other is process program running with user mode. By effective connection between two programs, system service becomes excellent. In traditional operating system, a system-call and up-call are used as connection mechanism of both. But these two methods have the weak point that overhead is big because of modification of execution mode and context switch. In this paper, I suggest mechanism displaying request/data (DRD) as new connection mechanism. Because DRD mechanism is not accompanied with modification of execution mode and context switch, it is connection mechanism with a little overhead. By implementation and evaluation, a DRD system shows that processing time is about 0.71 microseconds shorter than that of system-call.
