ABSTRACT:
A method and apparatus for linking two independent caches which have related information stored therein. Each unit of information stored in a first cache memory is associated with one unit of information stored in the second cache memory. Each unit of information stored in the first cache memory includes a pointer or index to the associated information unit in the second cache memory. Each information unit stored in the second cache is only stored once, regardless of the number of units in the first cache that are associated with a particular unit within the second cache. Therefore, even if more than one unit of information within the first cache memory is associated with the same unit of information within the second cache memory, that unit of information stored in the second cache memory is only stored once.
