The L1 cache may have been accessed to provide this data, which confuses it, if it ends up being accesses twice in one cycle. Instead wait 1 tick which will force the timing simple CPU to forward to its next clock cycle when the translation completes. Also prevent multiple outstanding table walks from occuring at once. |
