The current situation of China’s research and development of CPU chips and the famous inspirational couplets of the development team

First of all, let’s talk about the domestic CPU Loongson on the PC side. Loongson is a general-purpose CPU independently developed by the Institute of Computing Technology, Chinese Academy of Sciences. It uses a simple instruction set, similar to the MIPS instruction set.

The frequency of Loongson 1 is 266MHz and was first used in 2002.

The highest frequency of Loongson 2 is 1GHz.

Loongson 3A is the first domestic commercial 4-core processor with an operating frequency of 900MHz-1GHz.

The peak computing power of Loongson 3A reaches 16GFLOPS.

Loongson 3B is the first domestic commercial 8-core processor with a main frequency of 1GHz, supports vector operation acceleration, has a peak computing power of 128GFLOPS, and has a high performance-to-power ratio.

However, there is still a big gap between Loongson and the internationally renowned CPU manufacturers Intel and AMD.

Let’s talk about mobile CPUs. The first is Huawei’s HiSilicon processor. As the world’s leading ICT company, Huawei started the development of smartphone chips in 2006. The K3V2 launched in 2012 was the earliest real machine demonstration. , the smallest quad-core processor, becoming the first domestic high-end smartphone chip with a scale of tens of millions.

The Kirin processor launched later fully adopted the SoC (System on Chip, system on chip) architecture, which integrates a complete central processor, communication module, audio and video decoding, and peripheral circuits on a single chip. system.

At the same time, Kirin uses the current industry-leading 28nm HPM high-performance mobile process to meet the dual characteristics of high performance and low power consumption.

The upcoming HiSilicon Kirin 950 processor has caught up with or even surpassed the internationally renowned mobile CPU brands Qualcomm, Samsung exynos, NVIDIA, and MediaTek.

In addition to Huawei's HiSilicon Kirin, which is currently in use, the more well-known ones include MediaTek, Allwinner A10, Nufront, Rockchip, and Lianxin.

Among them, MediaTek currently has a considerable share of domestic mid- to low-end mobile phones. MediaTek mobile phone chips focus on low power consumption, so MediaTek’s mobile phone chips are more power-saving and have relatively excellent performance.
