Abstract
In a data processing system having a system bus for coupling I/O units to a system storage unit, there is provided a mechanism for supplying to the I/O units a line size signal representing the line size of the system storage unit. A further mechanism is located in at least one of the I/O units for responding to this line size signal for adjusting the data transfer size of the I/O unit to match the system storage unit line size.
