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.

@b Minimum toolchains requirements are shown below:

@section S0_1_contact Contact / Support

Please create an issue on <a href="https://github.com/ARM-software/ComputeLibrary/issues">Github</a>.

In order to facilitate the work of the support team please provide the build information of the library you are using. To get the version of the library you are using simply run:

    $ strings android-armv7a-cl-asserts/libarm_compute.so | grep arm_compute_version
    arm_compute_version=v16.12 Build options: {'embed_kernels': '1', 'opencl': '1', 'arch': 'armv7a', 'neon': '0', 'asserts': '1', 'debug': '0', 'os': 'android', 'Werror': '1'} Git hash=f51a545d4ea12a9059fe4e598a092f1fd06dc858

@section S0_2_prebuilt_binaries Pre-built binaries

For each release we provide some pre-built binaries of the library [here](https://github.com/ARM-software/ComputeLibrary/releases).

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.
