INFORMATION TRANSFER SYSTEM

摘要

PURPOSE:To attain simultaneous control or multiple address communication in the unit of optional groups by providing a variable receiving and processing number divided into an optional unit to each data processor or transferring control information and communication information to each data processor. CONSTITUTION:A transmission control circuit 12 edits a receiving and processing device number being a destination of information transfer and transfer information under the command of a processor 11 of a data processing unit 1-l requesting transmission, and transmits the result onto an information transfer bus 2 when the right of use of the bus is assigned by a right of bus use assigning circuit 3. Each data processing unit 1-l compares the receiving processing device number on the bus 2 with the receiving and processing device number assigned to a receiving control circuit 13 and the information transfer is attained by allowing the data processing unit 1-l having the coincident number to receive the transfer information on the bus 2 at the processor 11 as the receiving information.
