The reason why using cache can improve the running speed of computer

I would like to share with you the reasons why using cache can improve the running speed of computers. I believe most people don't know much about it, so share this article for your reference. I hope you will gain a lot after reading this article. Let's learn about it together.

Using cache can increase the speed of your computer because Cache reduces the wait time for CPU. The function of Cache is to increase the rate of CPU data input and output. Cache has small capacity but fast speed, low memory speed but large capacity. By optimizing the scheduling algorithm, the performance of the system will be greatly improved, as if the storage system capacity is equivalent to memory and the access speed is similar to Cache.

Cache memory, a cache memory in a computer, is a small but high-speed memory located between the CPU and the main memory DRAM (Dynamic Random Access Memory). It is usually composed of SRAM (Static Random Access Memory static memory). It is a small but high-speed memory located between CPU and memory. The speed of CPU is much higher than that of memory. When CPU directly accesses data from memory, it has to wait for a certain period of time, while Cache can save part of the data just used or recycled by CPU. If CPU needs to use this part of data again, it can be called directly from Cache, which avoids repeated access to data, reduces the waiting time of CPU, and improves the efficiency of the system. Cache is divided into L1Cache (first-level cache) and L2Cache (second-level cache). L1Cache is mainly integrated in CPU, while L2Cache is integrated on motherboard or CPU.
