Data Transfer Device for Heterogeneous Memory Systems

A system comprising:

• a processor;
• memory comprising a first memory space and a second memory space, the second memory space being heterogeneous to the first memory space;
• and
• a data transfer device configured to:
• receive a data transfer request from the processor;
• responsive to the data transfer request, obtain data from a first memory location in the first memory space;
• transfer the data from the first memory location to a second memory location in the second memory space;
• and
• optimize the transfer of the data from the first memory location to the second memory location by performing at least one data transfer operation.

A method comprising:

• receive, by a data transfer device, a data transfer request from a processor;
• responsive to the data transfer request, obtain, by the data transfer device, data from a source memory location;
• temporarily store, by the data transfer device, the data during at least one data transfer operation performed by the data transfer device to optimize transfer of the data between the source memory location and a destination memory location;
• and
• transfer, by the data transfer device, the data to the destination memory location.
