Method and apparatus for efficient, low-latency, streaming memory copies

Systems, methods, and apparatus with improved techniques for copying data from a source memory location to a destination memory location are disclosed. An exemplary method includes receiving a source address that indicates the source memory location, a destination address that indicates the destination memory location, and receiving a size indicator that indicates the size of the data. When the size is less than a threshold size, a particular pointer in a jump table is accessed, based upon the size that points to particular load and store instructions. The jump table includes a plurality of pointers that point to a corresponding one of a plurality of load and store instructions. The particular load-store instructions are then executed with a processor of the computing device to copy the data from the source memory location to the destination memory location. Several other efficiency-improvement aspects are also disclosed that may be used in connection with these steps to further improve copy efficiencies.
