Method and apparatus for direct conveyance of physical addresses from user level code to peripheral devices in virtual memory systems

摘要: A memory system and a set of user-level instructions that are callable from code for converting virtual addresses to physical conveying the peripheral devices without requiring call. The uses translation look-aside buffer (TLB) implemented in microprocessor. contents TLB can be updated while processes executing, allowing virtual/physical constantly loaded into too large. Pages use per transaction or job “pinned down” pinned page counts job, as well overall maintained.
