Abstract
A system for folding the address space of a reserved segment of a high speed memory into a designated part of the address space of a cache memory included in the high speed memory. Folding information for distinguishing between cache entries that have been folded from reserved segments and those that normally map into a designated segment of the high speed memory is stored. The folding information is utilized to determine whether a cache miss occurs when the designated segment of the cache memory is accessed.
