As of today, the Android operating system can only run on devices using Arm or x86 chips. Arm is usually used on mobile devices like phones, while x86 is usually on computers or TV dongles.
Google announced recently that Android will finally support chips with RISC-V architecture. RISC-V is an open source architecture, where chip manufacturers such as Qualcomm or MediaTek do not have to pay licenses as they do with Arm.
AOSP that supports RISC-V will also only support 64-bit, because that's the future, like the Pixel 7 which no longer supports 32-bit. Google also has high hopes for RISC-V and wants it to succeed. AOSP with RISC-V support will also support ART, where it enables many interesting features and functions such as applications that can run more smoothly and a more user-friendly system interface.
AOSP support with RISC-V is expected to start being offered to developers around this time. However, it is not certain if this year chip manufacturers such as Qualcomm or MediaTek will come out with RISC-V chips for a more affordable chip sales price so that smartphones that use this chip can also be sold at a cheaper price.
