Abstract:
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.
