Abstract

A pipeline interlock mechanism which insures the logical integrity of architected control quantities when used to access Domain Storage from Control State. A hardware Domain Interlock (DOMI) is provided to detect the start of execution in Control State of any instruction which modifies architected controls governing the access of Domain storage, and which insures that any subsequent potential access to Domain storage remains interlocked in the D-cycle until the modified controls become valid.
