The field of the invention is that of multiprocessor systems of the type comprising at least one processing module consisting of processors connected to a main bus, or of several processing modules communicating with one another through bus controllers. The aim is to furnish a bus deblocking system using a completely controlled process permitting gradual and repetitive deblocking of a multibus system experiencing general blocking. According to the invention, the method consists in conferring upon a specific deblocking card a function for detecting blockage of the module and a function for freeing the bus of the said module, the said function for freeing the bus consisting in emitting a single unblocking signal (45) causing, for all the processors of the module, on the one hand a disabling of the bus allocation system (34, 35) (operating by arbitration of simultaneous access requests (30)), and on the other hand a cancellation-setting of the bus control signal (37, 38). <IMAGE> |
