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.

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 year so far has been filled with news of Spectre and Meltdown. These exploits take advantage of features like speculative execution, and memory access timing. What they have in common is the fact ...

Caches are increasingly common in DSPs, but many DSP programmers are unfamiliar with their operation. This article explains how caches work, using the two-level cache in TI's C64x as an example. It ...

The authors report on the design of efficient cache controller suitable for use in FPGA-based processors. Semiconductor memory which can operate at speeds comparable with the operation of the ...

The development of caches and caching is one of the most significant events in the history of computing. Virtually every modern CPU core from ultra-low power chips like the ARM Cortex-A5 to the ...
