Abstract
A data processing system including a small throughput access source and a large throughput access source therein for accessing a main storage unit in a consecutive block access mode. The system further includes a detecting unit and a selecting unit. The detecting unit detects an access conflict expected to occur at the same address of the main storage unit. The selecting unit responds to the detection by the detecting unit and momentarily stops the access by the small throughput access source to give priority to the large throughput access source for accessing the conflicting address of the main storage unit.
