ABSTRACT:
A parallel processing search system for searching and updating a database at the request of a host system, including a master processor connected to a host system bus for transfer of information between said master processor and the host system bus; a data bus connected to the master processor; plural slave processors connected to the data bus for independently processing search respective requests under the control of the master processor; a disk drive interface adapted to be connected to a disk which stores a database; and a buffer memory connected to the data bus and the disk drive for storing the database retrieved from the disk and for sequentially placing data from the database on the data bus for match comparison by the slave processors so that a search of the database can be made by the slave processors under the control of the master processor. The buffer memory is also capable of storing updated data obtained from the host system via the master processor so that an updated database can be transferred to the disk memory via the disk drive interface.
