principle of caching is that when the CPU needs to read a piece of data, it first looks for it from the cache. if it finds it, it immediately reads it and sends it to the CPU for processing. If it does not, it reads data from the memory at a relatively slow speed and sends it to the CPU for processing. At the same time, it transfers the data block of the data to the cache, this allows you to read the entire block of data from the cache without calling the memory. This reading mechanism makes t
