The method comprises mapping a fixed memory-mapping control block in a host memory of the host to a control register of a memory-mapping unit of the PCI device; mapping a dynamic data-access memory block in the host memory to a default memory block in a memory of the PCI device, wherein the memory-mapping unit translates an address between the dynamic data-access memory block and a memory block in the memory of the PCI device; and dynamically modifying a value in the control register of the memory-mapping unit through the fixed memory-mapping control block such that an address of the dynamic data-access memory block in the host memory is translated to a different address in the memory of the PCI device based on the modified value in the control register of the memory-mapping unit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Device full memory access through standard PCI express bus","description":"A method of transferring data between a host and a PCI device is disclosed.
