This is true even in systems that only have a single execution core, and thus only have one thread actually executing at any given moment.

甚至在单核系统中也是一样的，只不过某一时刻仅有一个线程在执行。

Secondly, the issue logic is not only the critical path in a superscalar microprocessor, but also critical to the performance of a multithreaded microprocessor with superscalar execution core.

其次，指令发射逻辑是超标量处理器中的关键路径，也是制约执行单元为超标量结构的多线程处理器主频提高的关键因素。
