ABSTRACT:
A cache memory includes a dual or two part cache with one part of the cache being primarily designated for instruction data while the other is primarily designated for operand data, but not exclusively. For a maximum speed of operation, the two parts of the cache are equal in capacity. The two parts of the cache, designated I-Cache and O-Cache, are semi-independent in their operation and include arrangements for effecting synchronized searches, they can accommodate up to three separate operations substantially simultaneously. Each cache unit has a directory and a data array with the directory and data array being separately addressable. Each cache unit may be subjected to a primary and to one or more secondary concurrent uses with the secondary uses prioritized. Data is stored in the cache unit on a so-called store-into basis wherein data obtained from the main memory is operated upon and stored in the cache without returning the operated upon data to the main memory unit until subsequent transactions require such return. An arrangement is included whereby the real page number of a delayed transaction may be verified.
