Abstract
A circuit for controlling a cache system having a store queue having plural stages for storing store instructions. The circuit includes: a first comparator circuit for comparing, in view of index and off-set, an instruction with tag-retrieval to the store instructions stored in the store queue; and a stalling circuit for selectively stalling the instruction with tag-retrieval if the instruction with tag-retrieval corresponds, in view of not only index but also off-set, to at least one of the store instructions.
