System and method for performing a high-bandwidth memory copy. Memory transfer instructions allow for copying of data from a first memory location to a second memory location without the use of load and store word instructions thereby achieving a high-bandwidth copy. In one embodiment, the method includes the steps of (1) decoding a destination address from a first memory transfer instruction, (2) storing the destination address in a register in the bus interface unit, (3) decoding a source address from a second memory transfer instruction, and (4) copying the contents of a memory location specified by the source memory address to a memory location specified by the contents of the register. Other methods and a microprocessor system are also presented.
