: (A) instruction pre-fetech (B) instruction buffer (C) branching
: (D) cache misses (E) resource constrain
: will keep the pipeline from being full.
: 张凡给 a,b
: 可是keep the pipeline from being full 意思不是说,让pipeline不full吗?
正确
: 所以我想说是不是 d,e呢?
: c我没选是因为我想说,brach猜错的flush也是让pipeline full~
flush完后pipeline是空的
要等n(stage数)个cycle后才会full
: 请板上高手指点一下,谢谢~
