05_28_01_kernel_templates - Templates para Kernels L0

Propósito

Templates especializados para kernels L0 (operaciones atómicas DSP) con generación automática de variantes SIMD, benchmarks y tests de correctness.

Template Types

Arithmetic Kernels

• Binary operations (add, sub, mul, div)
• Unary operations (abs, sign, sqrt)
• MAC operations (multiply-accumulate)

Filter Kernels

• IIR filters (biquad, one-pole)
• FIR filters (convolution)
• State-variable filters

Transform Kernels

• FFT (radix-2, radix-4)
• Wavelet transforms
• Hilbert transform

SIMD Variants

Auto-generation of: - Scalar (reference) - SSE (4-wide float) - AVX (8-wide float) - AVX2 (8-wide float + FMA) - NEON (ARM)

Usage

audiolab-generate kernel \
  --name biquad_filter \
  --type filter \
  --simd auto \
  --benchmark

Entregables

• 15+ kernel templates
