Introduction
This repository is to provide a Rust crate to compute CRC-32C of data buffer on modern X86/ARM64 chips.
Algorithms, accelerated by SIMD intrinsics and mathematics manipulations, are described in reference 1 and 2
Goal
Ultimate benchmark performance should be something as below:
| Broadwell @ 3.00GHz | Skylake @ 3.20GHz | Ice Lake @ 2.40GHz | |
|---|---|---|---|
| crc32_4k | 10.19 GB/s 21.3 b/c | 12.64 GB/s 21.3 b/c | 11.59 GB/s 21.3 b/c |
| crc32_4k_pclmulqdq | 23.32 GB/s 48.8 b/c | 28.12 GB/s 47.5 b/c | 27.45 GB/s 50.5 b/c |
| crc32_4k_three_way | 26.99 GB/s 56.5 b/c | 33.26 GB/s 56.1 b/c | 29.18 GB/s 53.7 b/c |
| crc32_4k_fusion | 44.44 GB/s 93.0 b/c | 55.65 GB/s 93.9 b/c | 50.36 GB/s 92.7 b/c |
