Abstract

A bit or other vector may be used to identify whether an address range entered into an intermediate buffer corresponds to most recently updated data associated with the address range. A bit or other vector may also be used to identify whether an address range entered into an intermediate buffer overlaps with an address range of data that is to be loaded. A processing device may then determine whether to obtain data that is to be loaded entirely from a cache, entirely from an intermediate buffer which temporarily buffers data destined for a cache until the cache is ready to accept the data, or from both the cache and the intermediate buffer depending on the particular vector settings. Systems, devices, methods, and computer readable media are provided.
