sin32_simd.h File Reference

Detailed Description

Four-lane SIMD batch of fl::sincos32.

Split out of sin32.h so that the scalar sin32/cos32 LUT (reached from CRGB via ease.h and the fixed-point types) no longer drags fl/math/simd.h and the platform intrinsics into every translation unit. Include this header only where sincos32_simd() is actually used.

Namespaces
namespace	fl
	Base definition for an LED controller.

Functions
struct	fl::FL_ALIGNAS (16) SinCos32_simd
	Combined sin+cos result for 4 angles (raw SIMD primitives)
FASTLED_FORCE_INLINE SinCos32_simd	fl::sincos32_simd (simd::simd_u32x4 angles) FL_NO_EXCEPT
	Process 4 angles simultaneously, returning vectorized sin/cos values SIMD-optimized: vectorized angle decomposition, vector LUT loads with 4x4 transpose (AoS→SoA), and vectorized quadratic interpolation.
