Everything will go through a process from development to growth, to today's scale and processor achievements. History is interesting. As the whole core of a computer, we should simply explain it: temptation. Then the processor can always go back to 197 1.

197 1 year, when it was still in the development stage, Intel introduced the world's first microprocessor 4004. This is not only the first computer with four microprocessors, but also the ability to buy the first personal computer processor! ! 4004 contains 2300 transistors, and its function is quite limited, but its speed is still very slow. IBM is a blue giant who despises business users, but it is an epoch-making product. Since then, Intel has formed an indissoluble bond with microprocessors. It can be said that, in fact, the historical development of processors is the development course of Intel's X86 processor series, and we must start our historical journey of processors through it.

1978, Intel Corporation, once again leading the trend, took the lead in producing 16-bit microprocessors. Named i8086, it also produces a matching mathematical coprocessor i8087. These two chips take advantage of the compatibility of instruction sets, but in order to concentrate, i8087 specially adds some indexes, such as mathematical calculation and trigonometric function instructions. These instruction sets use i8086 and i8087. So the unified instruction set of these people is called X86 instruction set. Although Intel has produced the third generation of faster and more advanced new processors after the second generation. However, due to the trademark registration, the original X86 compatibility instruction Intel processor was still named later and followed the original X86 series until later. Continue to give up using Arabic names. As for the later development of other companies, such as AMD and Cyrix. The past 486 (486) was named X86 processor series according to a method of Intel processor. But in the 586 era, the market competition became increasingly fierce, due to the registration of trademarks. They can no longer use Intel X86 series with the same or similar names. In addition, 586,686 has its own compatible processor.

1979, Intel introduced a faster chip, still a 16-bit microprocessor. It contains 29,000 transistors, with a clock frequency of 4.77Mhz and 20 address buses. Use 1MB memory. The faster internal data bus is 16 bits. The external data bus is 8 bits, and its 8086 brother is 16.

198 1 8088 is the first IBM personal computer chip machine, opening up a brand-new computer era. It was developed from the concept of personal computers in 8088.

1982, INTE recently launched its latest landmark product, 80286 chip, which is a leap forward from the retail and development of 8006. Although it is still 16 bit structure, it contains134,000 transistors inside the processor. Gradually increase the clock frequency from the original 6Mhz to 20Mhz. It has 16 bit data bus, 24 bit address bus and 16 MB addressable memory inside and outside. From the beginning, the work has developed from two processors to real mode and protection mode.

1985 Intel introduced 80386 chip. It is the first in a series of 32-bit Intel 80X86 microprocessors, and it has also made great progress in manufacturing. While 80286 and 80386 contain 275000 transistors, and the clock frequency is 12.5Mhz, followed by 20Mhz, 25Mhz and 33Mhz. 80 and 386 are internal and external 32-bit data buses, and 32-bit address buses are. Up to 4GB of addressable memory. In addition to real mode and protected mode, it also adds a method called virtual 86. Emulation can also provide multitasking capabilities for more than 8,086 processors. In addition to the standard 80386 chip, that is, 80386DX, which we used to say in the past, for different markets and applications, Intel has introduced some other types of chips: 80,386,80386SX, 80386SL, 80386DL and so on.
