Abstract
PURPOSE: To increase the ratio of cost to performance, by executing the task represented for the priority having the highest priority by the processor designated with the processor designated information.
CONSTITUTION: The system consists of the main memory 1, first and second processor 2, 3, and input and output channel unit 4 connected to I/O 5, and the process control block information used for the control of processor usage right is stored in the unit 1. Further, the porcessor 2 consists of the sequential control section 31, interruption control section 32, semaphore control section 33, control section 34 selecting the task to be executed, memory access circuit 35, operation circuit 36 and register 37, and control sections 31 and 32 requests the start of the control operation with the control section 34 while relating to the contrl sections 33, and if there is no task under execution with the processor 2, the task having the highest priority among the task group possible for execution is found and the task corresponding is out of linkage from the queue by rolling in it.
