Aside from its main function of improving performance, cache memory is a valuable resource forevaluatinga computer's overall performance. Users can do this by looking at cache's hit-to-miss ratio. Cache hits are instances in which the system successfully retrieves data from the cache. A cache...

一是因为在Silicon Design中,很难在较短时间内产生一个随机数,即便使用最常用的LFSR(Linear Feedback Shift Register)机制也至少需要一拍的延时,而且也并不是真正随机的。二是因为多数程序具有Spatial Locality特性,依然在有规律地使用Cache,采用严格意义的Random很容易破坏这种规律性。 在许多实现中,Set Selection时选...

上图是 CPU 性能和 Memory 存储器访问性能的发展。 我们可以看到,随着工艺和设计的演进,CPU 计算性能其实发生了翻天覆地的变化,但是DRAM存储性能的发展没有那么快。 所以造成了一个问题,存储限制了计算的发展。 容量与速度不可兼得。 如何解决这个问题呢?可以从计算访问数据的规律入手。 我们随便贴段代码:for (j...

A cache is a buffer for data exchange. The essence of the cache is a memory Hash. Caching is a design that trades space for time, and its goal is to be faster and closer: a huge improvement. Write/read data to faster storage (devices); ...
以Cache为主体的memory hierarchy,在现代计算机架构中是名副其实的“半边天”。此外,了解Cache,不仅对了解CPU、GPU有重要的意义,对了解Linux Kernel也很有参考价值,此外,对Cache深入的理解,也会帮助性能调优,对写出高质量的软件大有裨益。 训练营课程大纲:
