Abstract
A method and device for sharing data. The method include: receiving, by a direct memory access controller, a data read instruction; wherein the read data instruction can be a shared data read instruction or a non-shared data read instruction; determining whether to fetch a requested data block from a first memory unit to a second memory unit by applying a direct memory address control operation; wherein the second memory unit is accessible by a processor that generated the shared data read instruction; fetching the requested data block from the first memory unit to the second memory unit by applying a direct memory access control operation, if the read data instruction is a non-shared data instruction or if the read data instruction is a shared data instruction but the requested data is not stored in the second memory unit; and retrieving a requested data block from a second memory unit.
