Abstract
A multi-source/receiver data processing system has a communication bus of at least one transfer medium. Clock signal generators have different clock frequencies with respect to each other. To prevent sources and/or receivers having a slow clock signal generator from being excluded as rightful participants from an action concerning a communication, the system determines whether said bus is 'ready' for executing an action using first and second detecting means whereby it can allocate a first and a second period of time thereto, respectively. When a source/receiver determines that this second period of time has expired, the bus is indeed ready for this source/receiver and all further source/receivers which have meanwhile determined during their first period of time that the bus in ready, so the bus can be occupied by this action.
