Abstract
This apparatus is used for minimizing the performance degradation due to address translation in computer systems employing random access memory and paging. It translates initial addresses into real addresses utilizing addressable memory and substitute paging. It decreases access time by not translating virtual address bits that are also real address bits and by commencing memory access using the available real address bits as they are available.
