<p>PURPOSE:To increase the using efficiency of a processor by changing a timer base value according to a time request from an application program and, simultaneously, preventing the generation of a software time interruption request when the timer request is not executed. CONSTITUTION:A software timer interruption control means 20 times the timer base value in a floating timer base table 22 based on interruption of a real time clock 1 from a timer means by setting the timer base value with a time base change managing means 23 to the floating timer base table and a software timer interruption is generated. Then, a time-out detecting means 21 times the timer value in the timer request based on the software timer interruption. Thus, the using efficiency of the processor can be increased.</p> |
