From meng wanzhou trapped overseas to smooth return, chip has become China's best known as one of the high-tech industry. Chip is the "oil" of the information age, the simpleton, iron core can not. Who can control chip, who can control the fate of the world.

Spectacular chip industry history, to remove the latter of the nearly 20 years to join China, chip industry players only 4: industry overlord of the United States, Japan, king former unique South Korea Europe, slowly but surely. Today, global chip industry for the 21st century - Japan, Europe, the United States firmly controls the materials and equipment in the industrial chain link, South Korea and China dominated the industry pattern of manufacturing and testing part. Global chip, all in a bag.

Aside from manufacturing, if traced back, domestic CPU design to roughly the following:

Others crack, burnish CPU, such as han core.

Authorization by the others on the basis of adding their own design, such as huawei haisi, authorization, after the ARM again design; Apple, samsung and qualcomm and mediatek, too;

Purchase a full range of solutions, on behalf of a super light of taihu lake with ShenWei series CPU;

Independent design + architecture compatible: in 2001 the godson was established by the Chinese Academy of Sciences computer group, launched in 2017 the godson 3. Because of the difference of the microstructure, the godson 3 performance only in the same period 35% of ADM and Intel chips, and using the authorization of the MIPS architecture. Released in July 2021, the division in the godson 3 a5000 processors, support independent LoongArch instruction system, compatible MIPS, ARM and x86 instruction set, marks the godson chips independent research and development success.
