    摘要： A system, method, and computer program product for semi-synchronously copying data from a first portion of memory to a second portion of memory are disclosed. The method comprises receiving, in a processor, a call for a semi-synchronous memory copy operation. The semi-synchronous memory copy operation preserves temporal persistence of validity for a virtual source address corresponding to a source location in a memory and a virtual target address corresponding to a target location in the memory by setting a flag bit. The call includes at least the virtual source address, the virtual target address, and an indicator identifying a number of bytes to be copied. The memory copy operation is placed in a queue for execution by a memory controller. The queue is coupled to the memory controller. At least one subsequent instruction is continued to be executed as the subsequent instruction becomes available from an instruction pipeline.

    摘要翻译： 公开了一种用于将数据从存储器的第一部分半数同步地复制到存储器的第二部分的系统，方法和计算机程序产品。 该方法包括在处理器中接收对半同步存储器复制操作的呼叫。 半同步存储器复制操作通过设置标志位来保持对应于存储器中的源位置的虚拟源地址和对应于存储器中的目标位置的虚拟目标地址的有效性的时间持续性。 该呼叫至少包括虚拟源地址，虚拟目标地址和标识要复制的字节数的指示符。 存储器复制操作被放置在队列中以由存储器控制器执行。 队列耦合到存储器控制器。 随着随后的指令从指令流水线可用，继续执行至少一个后续指令。

    摘要： A system, method, and a computer readable for protecting content of a memory page are disclosed. The method includes determining a start of a semi-synchronous memory copy operation. A range of addresses is determined where the semi-synchronous memory copy operation is being performed. An issued instruction that removes a page table entry is detected. The method further includes determining whether the issued instruction is destined to remove a page table entry associated with at least one address in the range of addresses. In response to the issued instruction being destined to remove the page table entry, the execution of the issued instruction is stalled until the semi-synchronous memory copy operation is completed.
