Compute Library

The Compute Library is a collection of low-level machine learning functions optimized for Arm® Cortex®-A and Arm® Mali™ GPUs architectures.

The library provides superior performance to other open source alternatives and immediate support for new Arm® technologies e.g. SVE2.

Key Features:

  • Open source software available under a permissive MIT license
  • Over 100 machine learning functions for CPU and GPU
  • Multiple convolution algorithms (GeMM, Winograd, FFT, Direct and indirect-GeMM)
  • Support for multiple data types: FP32, FP16, INT8, UINT8, BFLOAT16
  • Micro-architecture optimization for key ML primitives
  • Highly configurable build options enabling lightweight binaries
  • Advanced optimization techniques such as kernel fusion, Fast math enablement and texture utilization
  • Device and workload specific tuning using OpenCL tuner and GeMM optimized heuristics
