Access control method for multiprocessor systems |
摘要 |
In a multiprocessor system, a data transferring port into which data can be written only when no data is stored and from which data can be read only when it is stored is provided, and the port itself is caused to perform an exclusion control, whereby that processor of a plurality of processors which has once acquired a bus mastership is prevented from making another bus use request until the bus use requests of the other processors run out.
