The Compute Library is a collection of low-level machine learning functions optimized for both Arm CPUs and GPUs using SIMD technologies. The Compute Library is a collection of low-level machine learning functions optimized for both Arm CPUs and GPUs using SIMD technologies.
Several builds of the library are available using various configurations:
- OS: Linux, Android, macOS or bare metal.
- Architecture: armv7a (32bit) or arm64-v8a (64bit).
- Technology: Arm® Neon™ / OpenCL / Arm® Neon™ and OpenCL.
- Debug / Asserts / Release: Use a build with asserts enabled to debug your application and enable extra validation. Once you are sure your application works as expected you can switch to a release build of the library for maximum performance.
Minimum toolchains requirements are shown below:

Pre-built binaries
For each release we provide some pre-built binaries of the library here.
These binaries have been built using the following toolchains:
- Linux armv7a: gcc-linaro-7.2.1-2017.11-x86_64_arm-linux-gnueabihf
- Linux arm64-v8a: gcc-linaro-7.2.1-2017.11-x86_64_aarch64-linux-gnu
- Linux arm64-v8.2-a: gcc-linaro-7.2.1-2017.11-x86_64_aarch64-linux-gnu
- Linux arm64-v8.2-a (multi-ISA binary): gcc-arm-10.2-2020.11-x86_64-aarch64-none-linux-gnu
- Linux armv8.2a-sve: gcc-arm-10.2-2020.11-x86_64-aarch64-none-linux-gnu
- Android armv7a: clang++ / libc++ NDK r20b
- Android am64-v8a: clang++ / libc++ NDK r20b
- Android arm64-v8.2-a: clang++ / libc++ NDK r20b
- Warning
- Make sure to use a compatible toolchain to build your application or you will get some std::bad_alloc errors at runtime.
File organisation
This archive contains:
- The arm_compute header and source files
