Abstract

PURPOSE:To eliminate a complicated scheduler program and to delete the time overhead of a process switching operation, by incorporating a scheduler process swithcing hardware mechanism into a controller. CONSTITUTION:A memory 2 and an input/output device 3 are connected to a controller 1 via a bus 4 to form a stored program controller. A shceduler 10 is provided within the controller 1 to switch and control a switch mechanism 11. furthermore a scheduler control circuit 12, a process number memory 13 that has a cue structure and stores the process number within the controller 1, pre- and post-process registers 14 and 16 that control the mechanism 11 a process register 15 that stores and then transfers the process number which is being executed at an arithmetic device 8 are provided to the scheduler 10. Thus a complicated shceduler program is eliminated, and at the same time the time overhead is avoided for a process switching operation.
