Abstract
A block MOVE instruction allows a programmer to issue an instruction to a loosely coupled system bus controller, thereby facilitating the execution of a memory to memory move of multiple data entries, utilizing a burst mode transfer onto the system bus for both reads and writes. The instruction allows the programmer to fully utilize the maximum bus bandwidth of the system bus for memory to memory transfers of data (e.g. DMA, block moves, memory page initialization) and transfers of instructions/data to detached coprocessors.
