Module hexagon 

Available on target_arch=hexagon only.

Hexagon architecture intrinsics

This module contains intrinsics for the Qualcomm Hexagon DSP architecture, including the Hexagon Vector Extensions (HVX).

HVX is a wide SIMD architecture designed for high-performance signal processing, machine learning, and image processing workloads.

Vector Length Modes

HVX supports two vector length modes:

• 64-byte mode (512-bit vectors): Use the v64 module
• 128-byte mode (1024-bit vectors): Use the v128 module

Both modules are available unconditionally, but require the appropriate target features to actually use the intrinsics:

• For 64-byte mode: -C target-feature=+hvx-length64b
• For 128-byte mode: -C target-feature=+hvx-length128b

Note that HVX v66 and later default to 128-byte mode, while earlier versions (v60-v65) default to 64-byte mode.
