<p>PURPOSE:To realize an inter-process communicating means which can perform efficient duplex communication without increasing the amount of the hardware. CONSTITUTION:In an information processor provided with a means which assigns communication links to logical channels in a system in which two processes for making outputs and inputs are synchronized by making communication to each other by using one logical channel and protocol fixed to the logical channel, a pair of duplex links used for inter-process communication is provided and, at the same time, synchronization detecting mechanisms 3, 4, 8, and 9 which detect the synchronization between the processes from a communication request from one process and the information related to the communication request from the other process obtained from the synchronization detecting mechanism of the other process and means 7, 12, and 13 which give the using right of the duplex links to a relevant process on the basis of the information related to the synchronization between the processes from the mechanisms 3, 4, 8, and 9 are provided on both ends of the duplex links.</p> |
