英语语法分析

Therefore, for arbitrary addresses, we have no idea where in the loaded quadword the value we wanted is.

因而，对于任意的地址，我们无从知道在加载的四字中我们想要的那个值位于何处。

These all need to be quadword aligned, so that you can copy it into your main program and use the values with DMA transfers.

而且它们都是按四字节对齐的以便能够将其复制进您的主程序并在 DMA 传输时使用值。

The rotqby instruction, "rotate (left) quadword by bytes," USES the address you loaded from to indicate how far to rotate the register.

rotqby指令(代表的是“rotate (left) quadword by bytes”)使用加载自的地址以指示寄存器的旋转程度。
