摘要: A computer system (6,7) includes first and second I/O circuits (932, 934), buses (904, 83) respectively coupled to the a memory (106), third bus (104) interface (902, 6920) connected between respectively. direct access (DMA) controller (910) is (904) circuit (906), serial communications (7010, 6910, 7020) DMA (6920). As an example, in present invention single may be used provide capability both notebook docking station, using station transfer station. Other devices, systems methods are also disclosed.
