There are no less than 10 well-known CPU instruction sets in the world, and the most commonly contacted ones are x86 and arm, the former dominates the high-performance fields such as desktop, notebook and server, while arm is ubiquitous in smart phones, smart wear, embedded and other devices.
According to the data released by arm, in Q4 2019, its partners shipped 6.4 billion arm chips, of which 4.2 billion are Cortex-M series, which is aimed at the low-power embedded market,That's about 66 percentThe rest are all kinds of cortex-a, coretx-r, security chips, etc.
As for the familiar cortex-a series, arm is oriented to high-performance products, but the total volume is not the largest, because the total global shipments of smartphones, tablets and other devices are only about 2 billion, which is calculated to be up to 500 million per quarter, accounting for 10% of the total shipments.
If we consider the top-level cortex-a77 core, the proportion may be smaller,At present, only a few processors in the world, such as Xiaolong 865, Tianji 1000, exynos 990 and exnos 980, have adopted the a77 core. It is estimated that their market share has no statistical significance.
According to the data of arm company, from 1991 to now, arm company has shipped more than 160 billion arm chips in total, of which the first shipment in 26 years from 1991 to 2017 exceeded 100 billion.
But from 2017 to now, the speed of arm's shipment is faster. More than 60 billion arm chips have been shipped in three years, with an average annual output of more than 22 billion.
