Abstract
A data transfer system is disclosed for a computer system which includes at least one processor, a memory coupled to the processor, and two direct memory access selector channels. A hardware interconnection is provided between the two selector channels such that they can be used to transfer data from one portion of the memory system to another directly, using direct memory access techniques, without intermediate mass storage. The disclosed software provides a transfer system which mimics the use of magnetic tapes in many respects in order to simplify use of the system.
