ABSTRACT:
A command is decoded in a unit to provide bus-output-control information concerning the common bus busy state, and the existence of the command or the data. When the common bus is not available to the unit, the decoded bus out-control information, command and data are stored in the bus output stack. Immediately after the common bus becomes available to the unit, the decoded bus-output-control information is outputted to a control bus and the command and data which are stored in the bus output stack are outputted to the common bus. When the common bus is available to the unit, the bus-output-control information is outputted to the control bus, and the command and data are outputted to the common bus without going through the bus output stack.
