WebApr 17, 2024 · In I/O mapped I/O or isolated I/O mapping, the I/O devices are given a separate addressing ... Webmemory, with an access time of 1 microsecond per memory access. Thus, each memory reference through the page table takes two accesses. To improve this time, we have added an associative memory that reduces access time to one memory reference, if the page-table entry is in the associative memory.
