Patent abstract
The invention relates to a method for transferring data between a computer program executed by a processor and an input/output device using a memory accessible by the computer program and the input/output device. An operating system provides a trigger address range in a virtual address space assigned to the computer program. A page fault is caused by accessing the trigger address by the computer program. A page fault handler handling the page fault acquires information for identifying the data to be transferred using the trigger address. The acquired information is provided to the input/output device and the identified data is transferred between the memory and the input/output device.
