checking whether a use of the bus is secured in the presence of a communication data to be transmitted; requesting for the use of the bus when the bus is not secured; receiving the communication data and transmitting it to the bus of common resources; receiving only the communication data waiting for a reception when the bus is not secured; and processing the communication data. The method enables to use limited resources by allocating properly to process input/output data with multiple processors sharing common bus resources.
