Crate poulpy_cpu_ref 

Reference (portable) CPU backend for the Poulpy lattice cryptography library.

This crate provides two reference implementations for poulpy_hal:

• FFT64Ref: scalar f64 FFT arithmetic — see the fft64 module.
• NTT120Ref: scalar Q120 NTT arithmetic (CRT over four ~30-bit primes) — see the ntt120 module.

Both are canonical reference implementations: portable across all CPU architectures, prioritising correctness and debuggability over throughput.

Platform support

Compiles and runs on any target supported by the Rust standard library. No platform-specific intrinsics or assembly are used.
