    Unite Now would like to invite you to watch our upcoming "Using Burst Compiler to Optimize for Android" session.

    Join this session to learn how our partnership with ARM helps bring the power of the Burst Compiler to Android, enhancing multicore processor performance and power management. You’ll learn how Burst grants ahead-of-time compilation of critical C# code to native code and the features it enables (e.g., Advanced SIMD).

    Get started with Burst with this user guide and get Arm Mobile Studio here. Learn more about Arm and Unity's partnership.

    Hi, As per Android official site tells me that armeabi-v7a supports Thumb2 Instruction Set. And as per Burst documentation tells me that Arm32 Thumb2 is supported. So does it mean now all armeabi-v7a based devices as well as arm64-v8a devices are supported by Burst? Thanks.

    Arm Thumb is not an extension to the Armv7 instruction set. It's a mode when some instructions are coded using 1 byte in binary instead of 2, which allows to decrease the application size (which is important for Android). For example, the main Unity library libunity.so is compiled with thumb. IIRC, all Armv7 devices can run in Thumb mode, and there's no such thing as "support Thumb and don't support Armv7".

    Neon, on the other hand, is a set of SIMD instructions that are optional in armv7 and may not be supported by all devices. In practice, the last armv7 SoC that didn't support Neon was nVidia Tegra2 which is like 10 years old. Unity requires Neon support on Android since Unity 5. I think it's fair to say that Androids which don't support Neon are dead.

    Now, to answer your questions, Burst supports all Android devices which are supported by Unity. Thumb should not bother you, and you definitely must be focusing on ArmV8A (64-bit) and not the deprecated 32-bit tech.

    Hope that helps!
