  • The dynamic dispatcher present within AOCL-Compression executes the optimal function variant based on ISA supported by the runtime machine.

  • Optionally, AOCL optimizations can be restricted to certain ISAs by setting the environment variable AOCL_ENABLE_INSTRUCTIONS. Supported values are SSE2, AVX, AVX2 and AVX512.
