Document Type and Number:
Japanese Patent JP2836468
Kind Code:
B2
Abstract:
PURPOSE:To attain the two-layer scheduling with cooperation and the scheduling intended by the user and to reduce the execution time by allowing a task scheduler to recognize thread information managed by the operating system. CONSTITUTION:A task scheduler 101 requests thread generation to an operating system 102 based on divided tasks and a means 110 making generation request in the standby state when an optimum thread number 106 is exceeded. Furthermore, when a thread enters a sleep state, a means 112 uses to set a thread 103 in the standby state to an executionable state 104 so that number of executionable threads 104 is not less than an optimum thread number 106. In the switching state of tasks, the task scheduler 101 compares an executionable thread number 105 and the optimum thread number 106 and a thread standby processing means 111 is used to set the executionable not so as to exceed the optimum thread number 106 to the utmost.
