CONSTITUTING DEVICE FOR PLURAL PROCESSORS

摘要

PURPOSE:To grasp the executing state of a main process set on each processor when a processor constituting device falls into a state to be diagnosed, by providing a main process execution monitor means and a process switching state deciding means to each processor. CONSTITUTION:A command is fetched with execution of an input means and an executing means is carried out. Then a command concerned with exchange of messages between processors is easily carried out just by reading out the messages transferred between processors 14 through a CPU 18 on a shared memory 21. While the CPU 18 applies an interruption to a CPU 15 of a desired processor No.1 14 through a signal line 20 with a command concerned with the executing means for main process. The CPU 15 receives the interruption and carries out a process switching means stored in a memory for processor No.1 16 in the form of the interruption processing. Then a main process state saving means and a diagnosing process executing means are carried out.
