Abstract
Devices and methods provide data from multiple storage locations to a processor. A data block containing data required by a processor is stored in two or more locations, e.g., in a local memory and a system memory, both of which are accessible to the processor's memory interface. The memory interface directs each read request for mirrored data to one or another of the mirror locations. Selection of a mirror location to be read is based on substantially real-time information about which mirror location is best able to handle the request. For instance, the selection of a mirror location to access can be based at least in part on information about the level of activity on various buses that connect the processor to the mirror locations.
