1, but Huawei insisted on several mobile phones under pressure to use the chip, when Huawei chip was laughed at by everyone, and then Huawei began its own assiduous study.After two years of technical precipitation, in early 2014, Hisilicon released Kirin 910, and from here changed the chip naming method, as the world's first 4-core mobile phone processor, changed to Mali-450MP4 GPU. 2, in the war of the science and technology industry, the nirvana and rebirth of Huawei Kirin chip is undoubtedly the most eye-catching chapter. Let's review the brilliant history of Huawei's classic Kirin 9 series chip and witness how Kirin rose from frustration to the peak.
3. Kirin 990 5G is the most precise mobile phone chip designed by Huawei, and it is also the endToday's highest performance Huawei mobile phone Kirin chip. The CPU adopts a three-speed energy efficiency architecture with 2 super-large cores (based on Cortex-A76 development), 2 large cores (based on Cortex-A76 development) and 4 small cores (Cortex-A55). The maximum frequency can reach 86GHz, and the CPU cores of different sizes can be fine-tuned to achieve dual performance and energy efficiency improvement.
4, chip Kirin 990 Yesterday, Huawei consumer business CEO Chengdong Yu launched the latest generation of Huawei flagship chip for the world at the 2019 Consumer Electronics Show (IFA) in Berlin, GermanyIntegration into a small chip is a huge step forward.
Microchips are those small cuboids in electronic devices. Remember, the core of a chip is a small piece of IC. With the development of lithography technology, transistors became smaller and higher density in the early 1960s, ics rarely had more than five transistors because they could not be stuffed. However, in the mid-1960s, ics with more than 100 transistors began to appear on the market.
Jack Kilby. Integrated circuits have two main advantages over discrete transistors: cost and performance. The low cost is due to the chip putting all the components throughPhotolithography is printed as a unit, rather than making only one transistor at a time. The high performance is due to the fast switching of the components, which consumes less energy because the components are small and close to each other.
With the enhancement of the integrated chip function and the continuous expansion of the integration scale, the test of the chip becomes more and more difficult, the test cost is often higher than the design cost, the test cost has become an important part of the product development cost, the length of the test time also directly affects the product market time and then affect the economic efficiency. In order to keep the test cost within a reasonable limit, the most effective method is in the chip designDesign for testability (DFT) technology is used.
Year, the "National Integrated Circuit Industry Development and Promotion Outline" was introduced, and the national integrated circuit industry investment began to land, and the first batch of scale increased from the initial 100 billion yuan to 120 billion yuan. In 2015, The State Council issued "Made in China 2025", putting integrated circuits in the first place to develop a new generation of information technology industry.
Jack Kilby successfully integrated five components, including germanium transistors, and made a simple integrated circuit called a phase-shift oscillator based on the germanium material. andIn February 1959, he applied for a patent for a Miniaturized Electronic Circuit (patent No. 31,838,743, granted on June 26, 1964), which was the world's first germanium integrated circuit.
3, the size of the global integrated circuit market has fluctuated, and AI chips are the new direction. According to the statistics of the global Semiconductor Trade Statistics Organization, the global integrated circuit market size reached 330.4 billion US dollars in 2019, which fell from 2018. With the deepening of industrial information and intelligence, the size of the integrated circuit market will usher in a new upward trend, of which AI chips will become the mainstream technology direction leading industrial growth. In 2019, the global AI chip market was $11 billion.
4, combined with our previously published BAW filter quantityIt can be said that the RF shortboards in China's chip industry have been fully replenished, and a big step has been taken towards fully autonomous RF modules. Combing through the recent actions of the domestic RF chip industry, it is not difficult to find that pure wafer foundry independent chip designers have become an increasingly representative industrial route at the current point.
5, Taiwan chip industry is very strong, whether it is design or manufacturing or sealing test, Taiwan chip are very strong, can dominate the world in many aspects, Taiwan has four very strong chip companies, respectively, TSMC, LSMC, Taiwan Union power, the world advanced. These are the only companies that have ever66% of the world's total. Taiwan attaches great importance to the semiconductor industry and strongly supports the development of the semiconductor industry.
2, is an early 32-bit processor, introduced in 1985. 80486: The 80486 was introduced by Intel and has a unique place in the history of the X86 processor family because it was largely responsible for the leap in PC performance. Its main innovation was the introduction of internal caching,It laid the foundation for later CPU designs. Pentium Series: The Pentium is an Intel CPU family that began with the introduction of the first Pentium in 1993.
3, is a 16-bit processor; This architecture remained 16-bit until the development of the 32-bit 80386 in 1985. A series of processors followed, representing minor improvements to the 32-bit architecture, and several extensions were introduced until 2003, when AMD developed a 64-bit extension to this architecture and named it AMD64. Intel later introduced compatible processingAnd named Intel 64.
CPUFrom the initial development has been more than 20 years of history, during this period, according to the word length of its processing information, C PU can be divided into 4-bit microprocessors, 8-bit microprocessors, 16-bit microprocessors, 32-bit microprocessors and 64-bit microprocessors and so on.
CPU from the initial development has been more than 20 years of history, during this period, according to the word length of its processing information, the CPU can be divided into: 4-bit microprocessor, 8-bit microprocessor, 16-bit microprocessor, 32-bit microprocessor and is brewing to build 64-bit microprocessor, can be said to be the development of personal computersIt is advanced with the development of CPU.
Type: CPU if divided by performance, there are entry level, mid-end level, high-end level, fever level, these four levels. At present, there are mainly Intel and AMD two.
Intel processor classification: According to algebraic points, it can be divided into: the first generation of intelligent Intel Core processors. Second generation smart Intel Core processors. Third generation smart Intel Core processors. Fourth generation intelligent Intel Core processor.
Development history: Anything from development to growth will go through a process, CPU can develop to todayThe history of this scale and achievement is even more intriguing. As the "core" of the computer CPU is no exception, this article let us enter the time is not long but turbulent CPU development process. In the course of this review, we mainly describe the product development history of the two major CPU giants - Intel and AMD.
