题目内容
为了大幅度提高处理器的速度，当前处理器中采用了指令及并行处理技术，如超标量（Superscalar，）它是指（75）。流水线组织是实现指令并行的基本技术，影响流水线连续流动的因素除数据相关性、转移相关性外，还有（76）和（77）；另外，要发挥流水线的效率，还必须重点改进（78）。在RISC设计中，对转移相关性一般采用（79）方法解决。 78（）

In most parts of the United States, Friday night is the big supermarket night, probably because Friday is payday in many factories and businesses. Most housewives also do their weekend shopping on either Friday or Saturday, although supermarkets in many places are now open on Sunday as well.In almost all supermarkets there are shopping carts with a special space to set the baby. In the early days, before there were carts, it was noticed that as soon as a woman shopper had her arms full of goods, she stopped buying. Thus carts were introduced. Later a space for the baby was provided in the cart. With the baby sitting comfortably in the cart, the mother felt less need to hurry through the store and she would probably buy more. It is said that the average American housewife goes to the supermarket twice a week. On average she will spend from one hour to two hours there each week. Why did the supermarkets provide carts for their customers().

现采用4级流水线结构分别完成一条指令的取指、指令译码和取数、运算以及送回运算结果4个基本操作，每步的操作时间依次为60ns、100ns、50ns和70ns。该流水线的操作周期应为（60）ns。若有一小段程序需要用20条基本指令完成（这些指令完全适合于在流水线上执行），则得到第一条指令结果需（61）ns，完成该段程序需（62）ns。在流水线结构的计算机中，频繁执行（63）指令时会严重影响机器的效率。当有中断请求发生时，若采用不精确断点法，则将（64）。 60（）
