# PWN::FFI::Volk

Thin VOLK (Vector-Optimized Library of Kernels) binding. Dispatches to SIMD kernels (SSE/AVX/NEON/…) when the host provides them. Used by PWN::SDR::Decoder::DSP hot paths so MHz-rate I/Q work stays off the Ruby GC heap while orchestration remains pure Ruby. Nothing here shells out and nothing is compiled at gem-install time — if libvolk is missing, `.available?` is false and callers fall back.

## When to use

Call `PWN::FFI::Volk` from `pwn_eval` when the task needs this module.
Do not reimplement it in shell.

## Methodologies

Generated from `pwn/ffi/volk.rb`. Prefer the public class methods below.
Class methods take `(opts = {})` and read `opts`.
