其中没有标量(单元素)寄存器或操作。

There are no scalar (single-element) registers or operations.

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。

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.
