CPU高速缓存集成于CPU的内部，其是CPU可以高效运行的成分之一，本文围绕下面三个话题来讲解CPU缓存的作用： 从1->4,速度越来越慢，价格越来越低，容量越来越大。这样的设计使得一台计算机的价格会处于一个合理的区间，使得计算机可以走进千家万户。

The block of memory that is transferred to a memory cache. The cache line is generally fixed in size, typically ranging from 16 to 256 bytes. The effectiveness of the line size depends on the ...

A processor cache is an area of high-speed memory that stores information near the processor. This helps make the processing of common instructions efficient and therefore speeds up computation time.

If multiple devices, such as the CPU and peripherals, access the same cacheable memory region, cache and memory can become incoherent. This is illustrated in Figure 7. Suppose the CPU accesses a ...
