摘要
A storage apparatus receives a first and second access requests for accessing items in a same clock cycle. The apparatus includes two stores, each storing a subset of the plurality of items, the first access request being routed to a first store and the second access request to a second store; miss detecting circuitry for detecting a miss in the accessed store; item retrieving circuitry for retrieving an item whose access generated a miss from a further store; updating circuitry for selecting an item to overwrite in one of the two stores, the updating circuitry being responsive to the miss detecting circuitry detecting the miss in an access to the first or second store and to at least one further condition to update both of the two stores with the item retrieved from the further store by overwriting the selected items.
