Filed: 1989-11-24
Abstract: PURPOSE:To decrease the conflicting frequency of a system bus by monitoring via a control byte rewrite monitoring part whether another processing unit rewote the exclusive control byte of a main memory or not if the exclusive control byte is not equal to the prescribed value. CONSTITUTION:When the shared information is used, the bus controllers 11, 21 and 31 read the exclusive control bytes out of a main memory 5. These control bytes are transferred to the processors 10, 20 and 30 when the exclusive control byte comparing parts 12, 22 and 32 decide that the read exclusive control bytes are identical with the prescribed value. If not, the control byte rewrite monitoring parts 13, 23 and 33 monitor whether another processing unit rewrote the exclusive control byte or not. If so, the exclusive control byte is read out to decide repetitively whether the read control byte is equal to the prescribed value or not. Thus it is possible to reduce the reading frequency of the exclusive control bytes out of the memory 5 and to reduce the using frequency of a system bus.
