Macro gen_multi_transform_codelet 

gen_multi_transform_codelet!() { /* proc-macro */ }

Generate a vectorized multi-transform codelet.

Emits a function that processes V DFT transforms of size N simultaneously, where V is the SIMD lane count for the chosen ISA and precision.

The generated function name follows notw_{size}_v{v}_{isa}_{ty}.

Arguments

• size — DFT size: 2, 4, or 8
• v — number of simultaneous transforms (lane count)
• isa — target ISA: sse2, avx2, or scalar
• ty — float type: f32 or f64

Example

gen_multi_transform_codelet!(size = 4, v = 8, isa = avx2, ty = f32);
// emits: pub unsafe fn notw_4_v8_avx2_f32(...)
