<p>A communications control apparatus prepares for the generation of an interrupt signal along with appropriate address signals to retrieve data information from the main memory store upon the request from the central processor. During preparation time, a tag directory is searched for an indication that the data information required is presently in the cache store. If a comparison is made, a match signal is generated to prevent the generation of the interrupt signal. The communications control apparatus addresses the cache store to retrieve the data information for use by the processor.</p> |
