Abstract:

A new and useful DMA-like arrangement provides fast inter-system transfers of large data volumes. A preferred embodiment of the invention includes a data-transfer-out system and further includes a data-transfer-in system. At least one of the systems has a dual ported memory structure configured in a way so that data can move out of a memory module of the structure from one port while other data can independently move into the memory module through the other port. The systems are detachable with respect to each other, and the memory modules of both systems are correspondingly paired with compatible specifications such as module sizes. Furthermore, these memory modules are physically configured in a way so that inter-system data transfer occurs in a parallel (i.e., module to module) manner without the aid of the CPU of the system that has the dual ported memory structure.
