CPU USAGE RATE CONTROL DEVICE, CPU USAGE RATE CONTROL METHOD, AND CPU USAGE RATE CONTROL PROGRAM

摘要

PROBLEM TO BE SOLVED: To control CPU usage rate for each software module.SOLUTION: A CPU usage control device 1 includes mapping means 12 which generates a second thread of an OS layer for mapping to a first thread one-on-one each time the first thread is generated for executing a software module in an execution environment layer, group managing means 14 for managing a group in which the second thread is summarized for each software module, receiving means 16 for receiving a set value of CPU usage rate and a group of control object in the group, calculating means 15 for calculating CPU usage time of the second thread belonging to the group of control object on the basis of the set value of the CPU usage rate, and controlling means 11 for controlling CPU usage rate of the group of control object by using the CPU usage time.
