Abstract: The data record copy apparatus for a virtual memory system (120) instantaneously makes a copy of a selected data record (Record 4) by simply generating a new set of pointers (201-2) to reference the same physical memory location (214) as the original reference pointer (200-n). In this fashion, by simply generating a second set of pointers (201-2) referencing the same physical memory space (214), this apparatus effectively makes a copy of the data record (Record 4). A second physical copy of the data record (Record 4) can later be created as a background process or can be delayed until a modification is made to the data record (Record 4) by one of the two programs that access the data record (Record 4).
Abstract translation: 用于虚拟存储器系统(120)的数据记录复制设备通过简单地生成新的一组指针(201-2)来立即创建所选择的数据记录(记录4)的副本,以引用相同的物理存储器位置(214),如 原始参考指针(200-n)。 以这种方式,通过简单地生成引用相同物理存储器空间(214)的第二指针集(201-2),该装置有效地制作数据记录的副本(记录4)。 数据记录(记录4)的第二个物理副本后来可以被创建为后台进程,或者可以被延迟,直到通过访问数据记录的两个程序之一(记录4)对数据记录(记录4)进行修改 4)。

Abstract: The data record move apparatus for a virtual memory system (120) instantaneously relocates a selected data record (Record 1) by simply generating a new pointer (200-3) to reference the same physical memory location (212) as the original reference pointer (200-1). In this fashion, by simply generating a new pointer (200-3) referencing the same physical memory space (212), this apparatus effectively moves the data record (Record 1). The data record (Record 1) can be moved later as a background process or can be moved when a modification is made to the data record (Record 1) by one of the programs on the processor (100).
