out-of-order cores 是什么意思?难道是无序核吗?跪求计算机专业人士解答~
Similarly, the simple cores participating in a complex virtual core can be disjoined at any point of time. A canonical example is to form coalition of two 2-way out-of-order (ooo) cores to create a single 4-way ooo core. Thus we can create asymmetric multi-cores through simple reconfiguration.
