A data processing system has a store, logically partitioned into different partial spaces, for storing vector data consisting of different elements. The system also has address translation buffers, logically partitioned into pages of sizes prescribed for respective partial spaces, for translating the logical page number for each partial space to a physical page address. An address translation controller is provided for, when any of the vector data stored in the store is to be accessed and if the elements are within the range of a prescribed number of pages, searching different entries in the address translation buffers, performing simultaneous address translation of the pages, and thereby accessing the vector data. The number of simultaneously accessible elements is determined on the basis of the between-elements distance of the vector data and the size of the page of the partial space to which the desired vector data belong. The invention improves the efficiency of the store and increases the throughput of vector data processing.
