Abstract
An apparatus with an additional storage element or field is provided where a subscription indicator is stored, indicating a subscription to a region of memory, and hence subscribing to a cache line corresponding to the region of memory. In response to a subscribed cache line being invalidated, the apparatus performs actions to re-fetch the cache line, and to store the cache line in the cache after a short delay. The subscription indicator may be stored in a variety of ways, and may include further information that influences the functionality of the present techniques. Such further information may be adjustable in order to dynamically control the functionality of the disclosed techniques for a particular implementation over time.
