Abstract: Disclosed is a multiprocessor system in which even if contention occurs when a common memory is accessed from each of a plurality of processors, the number of times the common memory is accessed is capable of being reduced. The common memory of the multiprocessor system is provided with a number of data areas that store data and with a control information area that stores control information indicating whether each of the data areas is in use, and each processor is provided with a storage unit equivalent to the common memory and with an access controller. The access controller of a processor that does not have access privilege monitors data and addresses that flow on the common bus, accepts data written to the common memory and data read from the common memory, and stores this data in the storage unit of its own processor, thereby storing content identical with that of the common memory.

Abstract: The invention provides a connector having a pair of first and second connector housings for preventing looseness between the connector housings in lateral and longitudinal directions of the connector, surely eliminating frictional wear of male and female terminals in the connector housings. The connector can reliably resist to an external vibration force. A male connector housing 13 is resiliently urged by a waterproof packing 32 toward a female connector housing 36. The male connector housing 13 has an inner housing 25 formed with a plurality of looseness prohibiting projections 30. The looseness prohibiting projection 30 has a tapered surface 30a. An inner surface of a peripheral wall 39 of the female connector housing 36 is formed with a tapered surface 41 engaged with the tapered surface 30a on complete mating of the connector housings 13, 36.
