ABSTRACT:
An apparatus and a system, as well as a method and article, may operate to map, by an operating system, a range of virtual addresses to a range of physical addresses, wherein a subset of the range of virtual addresses is identity-mapped to a subset of the range of physical addresses. This range of addresses can then be used by heavy data transfer applications in conjunction with a DMA engine to transfer data between memories, or between memory and input/output devices.
