如今的计算机架构中CPU和main memory的访问速度的差异是很大的,解决这一瓶颈有这么几种形式: RAM硬件设计的改善(速度和并行) Memory controller设计 CPU caches 给设备用的Direct memory access(DMA) 2 Commodity Hardware Today 大众架构 Figure 2.1: Structure with Northbridge and Southbridge 所有CPU通过FSB连接到...
高速缓存(CPU Cache):使用静态随机存取存储器(Static Random-Access Memory,简称SRAM)的芯片。 内存(DRAM):使用动态随机存取存储器(Dynamic Random Access Memory,简称DRAM)的芯片,比起 SRAM 来说,它的密度更高,有更大的容量,而且它也比 SRAM 芯片便宜不少。 硬盘:如固态硬盘(Solid-state drive 或 Solid-state ...
aHaving half of the CPU and main memory resources does not mean a doubling of the response time but rather that only half the number of users can still work with the system in case of an emergency. 有CPU和主存储器资源的一半不意味加倍响应时间,但是仅那个一半用户的数量可能仍然宁可与系统一起...
二级缓存找不到去三级缓存查找。三级缓存还找不到就去主存（Main Memory）查找。这里说的主存，就是我们...
| | cache | | | | | +---+ +---+ | | | | ___ | | +---+ | | | Main Memory | | | +---+ 现在,我们在core 0上执行如下程序(a和b均初始化为0): a = 1; b = 2; 假设core 0的L1 Cache中没有a,但是有b。在core 0执行对a的...
了解下面各种策略,有利于理解Cache和Main Memory行为和配置Cache属性。 1. 各种策略行为和优缺点 Read Through:CPU Read data Through(not Allocate) Cache to Main Memory. Read Allocate:CPU Read data from Main Memory and Allocate it in cache Write Through:CPU Write data Through Cache to Main Memory。
Volatile main memory(易失性主存) Loses instructions and data when power off(断电) Non-volatile secondary memory Magnetic disk(磁盘) Flash memory(闪存) Optical disk (CDROM, DVD) 光盘 Networks 与其他计算机通信 Communication(通信), resource sharing(资源共享), nonlocal access(远程访问) ...
