    摘要: In computing environments that use virtual addresses (or other indirectly usable addresses) to access memory, the virtual addresses are translated to absolute addresses (or other directly usable addresses) prior to accessing memory. To facilitate memory access, however, address translation is omitted in certain circumstances, including when the data to be accessed is within the same unit of memory as the instruction accessing the data. In this case, the absolute address of the data is derived from the absolute address of the instruction, thus avoiding address translation for the data. Further, in some circumstances, access checking for the data is also omitted.

    摘要翻译: 在使用虚拟地址(或其他可间接使用的地址)访问内存的计算环境中,在访问内存之前,将虚拟地址转换为绝对地址(或其他可直接使用的地址)。 然而,为了便于存储器访问,在某些情况下,包括当要访问的数据与访问数据的指令在同一个存储单元内时,省略了地址转换。 在这种情况下,数据的绝对地址是从指令的绝对地址导出的,从而避免数据的地址转换。 此外,在某些情况下,也省略对数据的访问检查。
