摘要： A data processing system executes two instruction sequences in an order determined in advance. The executions include selection of read/write instructions (4) containing read/write addresses. With the aid of the instructions, a separate memory (1) assigned to respective sequence is activated for data information reading/writing. The separate memories are mutually updated with regard to the order and the write instructions (3). During execution of the sequence which is second due to the order, data information is used which is not guaranteed in advance as being independent of the data information obtained during execution of the sequence which is first due to the order. Increased data handling capacity is achieved in the following manner: both sequences (5) are executed in parallel to start with. An address included in a read instruction associated with the second sequence is intermediate-stored if this address has not been previously selected in conjuction with a write instruction associated with the second sequence (41, 42). The intermediate-stored address is compared with the write addresses of the first sequence and execution of the second sequence (56, 60, 61, 62) is restarted upon likeness in addresses.
