Computer system and method for enhancing memory-to-memory copy transactions by utilizing multiple system control units

摘要

A computer system and method for enhancing memory-to-memory copy operations includes transmitting from the processor to the source system control unit a plurality of memory-to-memory copy transactions where each transaction includes a source address and a destination address. A lookup operation is performed on the destination address to determine the destination system control unit that controls access to the destination memory which contains the destination address. A number of data blocks located at the source address in the source memory are retrieved and transmitted to the destination address. The number of data blocks are stored at the destination address in the destination memory.
