Abstract
In one embodiment, a data movement module (DMM) may receive a command to copy data from a source buffer to a destination buffer. One or more cache lines corresponding to addresses of the source buffer and the destination buffer may be invalidated. Also, an entry may be added to a queue to indicate that the command to copy is completion pending.
