获取cache 参数有下面两种方法:分别是当CPUID指令Initial EAX Value为0x02和0x04时候,由于方法一种CPUID指令的入口参数存放在EAX寄存器中,所以获取cache信息需要给EAX寄存器赋值为0x02,然后分别读取EAX、EBX、ECX、EDX四个寄存器得到Cache and TLB Information。
但是很多情况下cpu只需要这一个cache line的某些word，因此这时候block size的增大意味着更多的带宽被浪费...

CPU在片内缓存——也就是cache方面下功夫,一直都是CPU微架构更新的老传统。这两年我们讨论最多的,莫过于AMD的3D V-Cache(以下简称V-Cache)——一种把L3 cache三级缓存垂直叠起来的方案,增大处理器的L3 cache容量。 最近又有传言说,Intel接下来要发布的14代酷睿可能...
