As early as 2015, apple began to urge developers to submit 64 bit applications to improve efficiency and security. After 2017, the IOS platform completely abandoned 32-bit app and realized 64 bit.

Last year, Google began to promote 64 bit Android platform, and will no longer provide follow-up updates for existing 32-bit programs after next August.

As a developer of CPU instruction set architecture for IOS and Android devices, arm announced at the developer summit held this week,Starting from 2022, its cortex core CPU will cancel 32-bit support。

Since big.LITTLE size kernel design is very common in current mobile SoC, it is not clear whether these chips can support the operation of 32-bit programs.

Judging from the road map shared by ARM, the 2022 nuclear CPU architecture code Makalu( Himalayan Makaru Peak), performance is about 30% higher than Cortex-A78. However, usually, the new public version of the large core architecture will take a year to be Qualcomm, MediaTek and other enterprises to absorb into the SoC design and commercial.
