科技 Crash Course But it's still many times slower than your computer's RAM. For this reason, computers today still use memory hierarchies. 但它仍然比您计算机的 RAM 慢很多倍。出于这个原因,今天的计算机仍然使用内存层次结构。 科技 Crash Course This is an example of a memory hierarchy, where you have a little bit of fast memory, which is expensive, slightly more medium-speed memory, which is less expensive, and then a lot of slowish memory, which is cheap. 这是内存层次结构的一个例子,其中有一点快速内存, 价格昂贵,中速内存稍多一点, 价格便宜,然后是很多速度较慢的内存, 价格便宜。

内存阶层内存阶层是在电脑架构下保存系统阶层的排列顺序。每一层于下一层相比都拥有较高的速度和较低延迟性,以及较小的容量(也有少量例外,如AMD早期的Duron CPU)。 大部分现今的中央处理器的速度都非常的快。大部分程序工作量需要内存访问。由于缓存的效率和内存传输位于阶层中的不同等级,所以实际上会限制处理的速度,导致中央处理器花费大量的时间等待内存I/O完成工作。 大部分电脑中的内存阶层如下:

Memory hierarchy 记忆体阶层![]() ![]() ![]() ![]() In computer architecture the memory hierarchy is a concept used when discussing performance issues in computer architectural design, algorithm predictions, and the lower level programming constructs such as involving locality of reference. The memory hierarchy in computer storage distinguishes each level in the hierarchy by response time. Since response time, complexity, and capacity are related, the levels may also be distinguished by their performance and controlling technologies. |
