This article is about where computer instructions are stored. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Computer instructions are mainly stored in memory. Memory cell is actually a kind of sequential logic circuit, which is a collection of many memory cells, arranged in order of cell numbers. In order to improve the performance of memory, all kinds of memory with different storage capacity, access speed and price are usually composed of multi-layer memory according to hierarchical structure.

Computer instructions are mainly stored in memory.

Memory unit is actually a kind of sequential logic circuit. According to the use type of memory, it can be divided into read-only memory (ROM) and random access memory (RAM). The functions of the two are quite different, so they are also different in description.

A memory is a collection of many memory cells, arranged in order of cell numbers. Each cell consists of several ternary bits to represent the values stored in the memory cell, this structure is very similar to the structure of the array, so in the VHDL language, the memory is usually described by the array.

In order to improve the performance of memory, all kinds of memory with different storage capacity, access speed and price are usually composed of multi-layer memory according to hierarchical structure, and are organically combined into a unified whole through management software and auxiliary hardware. so that the stored programs and data are distributed in each memory in a hierarchical manner.

The storage system is mainly composed of three-level hierarchical structure, which is composed of cache Cache, main memory and auxiliary memory. In the figure, the capacity increases gradually from top to bottom, the speed decreases step by step, and the cost decreases step by step.

Thank you for reading! This is the end of the article on "where computer instructions are stored". I hope the above content can be of some help to you, so that you can learn more knowledge. If you think the article is good, you can share it for more people to see!
