Abstract

PURPOSE: To control a resource wait time and a response time by causing the value of a ratio of a task resource occupation time to the resource wait time to approach a designated value and estimating the resource occupation time on a basis of processing contents.
CONSTITUTION: The representative difference between the value, which is designated for every task, of a ratio of a resource occupation time to a resource wait time and the value of a ratio of a solid-measurement resource occupation time to a solid- measurement resource wait time concerning task which are calculated from values obtained by a mechanism to measure actually the resource occupation time and the resource wait time is operated, and the resource is preferentially assigned to a task where this difference is larger respresentatively, and this difference is controlled to approach 0 as possible. As a result, the of value the ratio of the solid-measurement CPU occupation time to the solid-measurement CPU wait time in case of task running can be caused to approach the value, which is set in task control memory TCM as a designated occupation wait time ratio, as possible.
