Module `hexagon`

Hexagon architecture intrinsics

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

Scalar Intrinsics

The scalar module provides intrinsics for scalar DSP operations including arithmetic, multiply, shift, saturate, compare, and floating-point operations.

HVX Vector Intrinsics

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

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.
