DYNAMIC ADDRESS TRANSLATION WITH LOAD REAL ADDRESS
摘要
<p>What is provided is a load real address function defined for a machine architecture of a computer system. In one embodiment, a machine instruction containing an opcode is obtained indicating that a load real address is to be performed. The instruction further identifies a first general register. Based on the contents of the machine instruction, a virtual address to be translated is obtained. Dynamic address translation is performed on the virtual address to obtain a segment-frame absolute address of a large block of data in memory. If an extended DAT facility and a format control field in the segment table entry are enabled, the address of the block of data is saved in the first general register. A page index portion and a byte index portion of the virtual address may also be saved in the first general register.</p>
