Abstract:
An apparatus has a cache configured to store entries which correspond to blocks of addresses having one of a plurality of sizes as selected by a control device. When the control device has not yet indicated which size to use, cache access circuitry assumes a default size which is greater than at least one of the plurality of sizes.
