The instruction cache memory processor in a multithreaded processor includes a barrel shaped thread execution unit for executing concurrent threads, and a duplicate cache memory shared between concurrent threads
cache memory: optimizes speed by reducing data access time. virtual memory: enhances memory capacity, allowing systems to handle more extensive processes. location: cache: located near the cpu and built directly into the processor or on a separate chip. virtual memory: utilizes the computer’s ...

这使一系列Index-Aware类的Memory分配算法得以引入。在介绍这些Memory分配算法之前,我们首先介绍采用分页机制后,一个进程如何访问Cache,其示意如图2‑8所示。 在多数情况下,操作系统以4KB为单位将Memory分解为多个页面。如上图所示,这个4KB的页边界将Cache Line Index分解成两个部分,其中在Page Frame中的部分被称为Bi...

这篇文章最初的版本是0.01,书名叫浅谈Cache Memory。 第一章 1.1 关于Cache的思考 在现代处理器系统中,Cache Memory处于Memory Hierarchy的最顶端,其下是主存储器和外部存储器。在一个现代处理器系统中,Cache通常由多个层次组成,L1,L2和L3 Cache。CPU进行数据访问将通过各级Cache后到达主存储器。如果CPU所访问的数...
Level 2 (L2) is also called the “secondary cache.” It’s where your computer goes when it can’t find your data (or gets a “miss”) after looking in the L1 cache. Level 2 is usually on a memory card in close proximity to the processor. ...
《What Every Programmer Should Know About Memory》是Ulrich Drepper大佬的一篇神作,洋洋洒洒100多页,基本上涵盖了当时(2007年)关于访存原理和优化的所有问题。即使今天的CPU又有了进一步的发展,但是依然没有跳出这篇文章的探讨范围。只要是讨论访存优化的文章,基本上都会引用这篇论文。

The cache uses predictive algorithms to forecast which information will be required next. It preloads them into its storage space before the processor asks them, resulting in zero wait time. What Is the Purpose of Cache Memory Cache memory is beneficial in many cases as it helps r...
