  • Hierarchical data store with look-ahead action
    Patent number: 4086629
    Abstract: A hierarchical data storage system comprises a main store and a smaller, faster slave store containing data currently required for processing. The memory system responds to a store access command to retrieve an item of data. In addition, for certain types of store access command, the system performs a look-ahead action to ensure that the slave store is loaded with another data item which forms part of a possible sequence. In certain cases, a test is made to determine whether the possible sequence is in the ascending or descending direction, and the look-ahead access is then made in the appropriate direction.
