Abstract
An apparatus and method for organizing a data array within a cache system to store a plurality of physical pages of data. A single data array is associated with a plurality of tag arrays, each tag array tracking a page size portion of the data array. Indexing into each of the tag arrays is accomplished using the page index from either of the virtual address or the physical address. In addition, selection of indexed tags from the tag arrays is performed by array selection logic which utilizes portions of either of the virtual page number or the physical page number.
