METHOD AND CIRCUIT FOR SYNCHRONIZATION BETWEEN PROCESSORS

摘要

PROBLEM TO BE SOLVED: To easily and speedily synchronize processors in operation in a multiprocessor system. SOLUTION: Processors 10a and 10b which request themselves to be synchronized with each other a read access to the synchronizing circuit 21. The synchronizing circuit 21 pass answer data showing that the synchronization is successful to the processors when the read access from the processors is completed within a predetermined time. When not, on the other hand, the circuit passes answer data showing that the synchronization ends in failure to the processors.
