Abstract
An improved mechanism for copying data in memory is described which uses aliasing. In an embodiment, data is accessed from a first location in a memory and stored in a cache line associated with a second, different location in the memory. In response to a subsequent request for data from the second location in the memory, the cache returns the data stored in the cache line associated with the second location in the memory. The method may be implemented using additional hardware logic in the cache which is arranged to receive an aliasing request from a processor which identifies both the first and second locations in memory and triggers the accessing of data from the first location for storing in a cache line associated with the second location.
