我们将这个过程可以表示如下： 其实现实中，CPU通用寄存器的速度和主存之间存在着太大的差异。两者之间的速度大致如下关系： CPU register的速度一般小于1ns，主存的速度一般是65ns左右。速度差异近百倍。在硬件上，我们将cache放置在CPU和主存之间，作为主存 ...

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 ...

编者按：1月8日晚上，《深入理解cache训练营》讲师甄建勇和阅码场资深用户wisen围绕Cache和性能优化展开了一场线上圆桌讨论。本文是对圆桌内问题的解答整理，不一而详，供大家参考。感谢阅码场用户王建峰对于问题的整理。 例如，我在商场购物时，把要买的 ...

We have described and applied a technique for selection of processor cache configurations for low power using a parameter defined as a product of the cache miss rate and cache size. 1. Introduction ...

The memory hierarchy (including caches and main memory) can consume as much as 50% of an embedded system power. This power is very application dependent, and tuning caches for a given application is a ...
