Abstract
A logical cache memory has a logical tag and a physical tag as address tags for comparison, and status information representing their status. Data status and block status are registered at the same entry position. When access is made using a logical address, access is made to the logical tag to detect the existence of data, and when access is made using a physical address, access is made to the physical tag using an offset portion which does not depend on address conversion, to detect the existence of data.
