Abstract
A unique high-speed hardware arrangement for generating double-level address translations in combination a translation look-aside buffer (TLB) structure that can store and lookup intermediate translations during a double-level translation. The hardware proceeds to the completion of a double-level translation without having to backup its operation, although an intermediate TLB miss is encountered, without danger of CPU deadlock occurring. The hardware arrangement also performs all single-level address translations required by the system.
