In an SISD architecture there is a single instruction cycle; operands are fetched serially into a single processing unit before execution.
在单指令流单数据流结构中，有单一的指令周期，在执行前，单个处理机按序取操作数。
The basic operating cycle of a processor during which a single instruction is fetched, interpreted, and executed.
基本操作周期的处理器在一个单独的指令是拿来，解释和执行。
In Chapter 2, we learned that the processor fetches and executes a single instruction during each machine cycle.
在第二章中，读者知道了在每个机器周期内处理器取出并执行一条指令。
Another unique architectural feature is the memory system which allows an instruction fetch and at the same time a data access by each individual core at every single clock cycle.
另一个独特的构架特性是内存系统，它允许一个取指，并在同一时间，每一个核可以读取数据在每一个单独的时钟周期内。
